In this video, Mahalo math expert Allison Moffett explains how to use the powers of ten.
Powers of Ten
---------------------------------------------------------------------
When you're multiplying the number 10 by itself, you can write it a different way using positive exponents. The exponent tells you how many times the number should multiply by itself. For example, 10 to the power of 2 means 10 times 10. 10 to the power of 3 means 10 multiplied 3 times. If you're starting out with an expanded number and want to find the exponent form, count the number of zeros. The number of zeros will determine your exponent. 10,000 is 1 with 4 zeros, so it's 10 to the power of 4.
Special Cases
---------------------------------------------------------------------
10 to the power of zero and 10 to the power of 1 are special cases. Any number to the power of 1 will equal itself. Any number to the power of zero will equal 1.
