One litre of water in itself is a volume that is equal to 1000 cubic centimeters. We often overlook the significance of exponents in our lives. The smaller unit, mega, is 1 followed by 6 zeros, which equals a million. Do you recall how much is a Giga equal to? Giga is 10 9, that's 1 followed by 9 zeros. If we ask you how fast your mobile is, you say it has a 2 GHz processor, right? Here, GHZ means giga hertz. So what do you do? You multiply 12 by 12, which as 12² = 144 square feet.

So you now simply need to know how big your room really is. To understand it better, suppose your bedroom is 12 feet by 12 feet. The area of a geometric shape is in squares, while the volume is in cubes. If the value of the base is a negative number, the value entered in the exponent field will determine whether the answer will be a positive integer or a negative one.įor example, if you enter the base as -5, its square will be 25, its cube will be -125, -5 4 is 625, and so on. Just make sure the value of power must be a positive integer. This online calculator will give you the right answer every time. You simply need to enter the value of the base number, enter the value of how much you want it to raise to the power of, and that's it. How did you solve exponents in school? The teacher simply asked you, 'what is 3 raised to the power 4?' And you simply multiplied 3 by itself 4 times, right? iCalculator developed the mathematics power calculator using the same concept.

When multiplying two or more powers with the same base simply, you simply need to add the exponents:Īnd so on How to use the mathematics power calculator The properties of the exponential function are better understood by the operations we can do on powers: Exponent Example 1 In its textbook definition, an exponential function is a number with a positive real number in the superscript where the number in the exponential form equals how many times the real number must be multiplied by itself. But before we talk about this math calculator in detail let's take a look at the exponential function in detail. This is where a mathematics power calculator comes into the picture. Like the square of 15 (225), or square of 25 (625), or cube of 4 (64), or 3 4 (3 x 3 x 3 x 3 = 81).īut as the numbers go higher and the exponential power increases, finding the right answer starts becoming more and more difficult.

Historical note: EE stands for Engineering Exponent. That's nice, but not completely necessary. Some calculators have a mode such that when you press something like EE 4, it will print 10 4. This calculator was not set up to use scientific notation for numbers in the 1000 range. Notice that the 3 rd result was displayed as 4613.333. On this calculator it's done using the button. You can set your calculator to display results in scientific notation if you'd like. See if you can follow the rest of those calculations. On the calculator shown here, EE is the 2nd function of the comma (, ) key.įour calculations – two multiplications and two divisions – have been entered and performed on this calculator. Both are a shorthand for ' times ten to the power of.'įor example, if I want to enter 2.48 x 10 19, on the calculator on the left, I enter the sequence ' 2.48 EE 19'. On most calculators, we enter scientific notation using a button labeled EXP or EE. To move the decimal between the 2 and the 3, we'll need to move it five places to the left: This example is similar to the first, except that there is actually a decimal in the original number. Note that the number in scientific notation is really a kind of recipe for recovering our original number: 'Take 1.2 and move the decimal 7 places to the right.' When we're forming the scientific notation, the move is in the opposite direction, but that's only to form 1.2 x 10 7 in the first place. It's 1.2 with 6 zeros (the 7 th place is taken up by the 2): Now it's a simple matter to form the number in scientific notation. Now we simply count how many spaces from the right (the original decimal) that is:

Example 1: 12,000,000įirst, there is an implicit (not shown but there) decimal after 12,000,000, and our goal is to put it after the 1 and before the 2: This is one of the tasks you may have to do most, so it's a good one to learn. Here are a few examples of how to convert numbers, big and small, to scientific notation.
