Saying "3 to the power of 4" or 3 4 is the same as saying 3 times 3 times 3 times 3 (equals 81). Saying "20 to the exponent 4" or 20 4 is the same as saying 20 x 20 x 20 x 20 (equals 16,000). To find a number to a different power, use our simple exponent calculator. To find the number needed to find the exponent 4 of a number, use the Counting by powers of ten: Counting to ten billion on your fingers ten, hundred, thousand, ten thousand, hundred thousand, million, ten million, hundred million, billion, " One: 10 0: 1. "ten to the zero" ten: 10 1: 10. "ten to the one" hundred: 10 2: 100. "ten to the two" thousand: 10 3: 1,000. "ten to the three" ten thousand: 10 4: 3 Answers. If you need to typeset actual numbers (and not symbols as in your example), you could use the \num macro provided by siunitx. It allows you to type \num {2e3} to output , both in math and in text mode. When multiplying numbers in exponential form, you could reduce the spacing within the numbers, using tight-spacing=true: The mathematics power calculator is a simple maths calculator that tells you how much a number equals in its exponential form. We are talking about squares, cubes and higher exponential powers here. For example: if you are asked to find out the square of 5, 5², you'll simply need to multiply 5 by itself: 5² = 5 x 5 = 25. Find the value of the exponent. Let's say that you're working with trying to find 10 2. In this case, the positive integer you're working with is 2. [3] 2. Subtract 1 from the value of the exponent. In this case, 2-1 = 1, so you're left with 1. 3. Write this many zeroes after "10" and you're all done. t0cwaJu.
