Question

"Write 1/100 using a negative exponent other than -1. Answer: 10^-2." Why is 10^-2 the answer?

Answer 1

They want you to write 1/100 using a negative exponent other than -1. 10 is the square root of 100, because 10 x 10 is 100. A negative number times a negative number is a positive number. So, 10^-2 is the same as -10 x -10, which is equal to 100.

10^-2

= -10 x -10

= 100
