what is 10^-2?
10 to the power of negative 2
No. You moved the decimal three places. It should be moved two places so the answer is .01 but I like to place a zero BEFORE the decimal point so that it is obvious that the number is 0.01. Sometimes the decimal point doesn't show up well in small print but the zero there before makes us aware that the decimal point is there.
ok i see.
im still not sure exactly how u figured out the answer.is there another way to explain?
a^(-n) = 1/(a^(+n)), one of the basic rules of exponents.
so 10^-2
=1/10^2
= 1/100
= .01
