10x10x10x10x10
The answer is... 100,000
It is: 105 = 100,000
10x10x10x10x10=100000
10x10x10x10x10
This is 10x10x10x10x10=110 put ten small next to the 1
10 to the 5th power is 10x10x10x10x10 which equals 100000
10^5 means 10x10x10x10x10. 10^3 means 10x10x10. Multiplying them together is 10x10x10x10x10 x 10x10x10 which is 10^8. In general, x^a times x^b is x^(a+b).
x to the nth power means n lots of x's, all multiplied together. In this case, 10 to the 5th power, or 105 would mean 10x10x10x10x10 = 100,000 20 times this is 20x100,000=2,000,000 Thus, 20 times 10 to the 5th power is 2 million.

In math, there are many terms that have to do with multiplying a number times itself. An example is 3 x 3 =9 Two identical numbers multiplied together gives an answer "To the power of 2". '9' is "3 to the power of 2" because 3x3=9. (2 3s . . . power of 2) Multiply 3 identical numbers, say, 5x5x5 = 25. So '25' is "5 to the power of 3". Multiply 4 identical numbers, say 1x1x1x1. So '1' is "1 to the power of 4". Or, 2x2x2x2 = 16, so '16' is "2 to the power of I bet you see where this is going: Ohhh, how about 10x10x10x10x10 = 100,000, so '100,000' is "10 to the power of 5".
