That is the definition of negative powers.
it is a positive fraction 5^-2=1 over 5^2 answer is 1 over 25
6 to the negative 2nd means that it equals 1 over 6 to the negative 2nd.
1 over 5^2. which is 1/25
They are not! 5-3, for example is not 1/52 nor (1/5)2.

6 to the negative 2nd means that it equals 1 over 6 to the negative 2nd.
A negative exponent is 1 over the base to the power of the absolute value of the exponent. For example 2 to the power of -1 is 1/2, 2 to the power of -2 is 1/4, or (1/2) squared, and 2 to the power of -3 is 1/8, or (1/2) cubed.
1 over 5^2. which is 1/25
The negative means " 1 over it" so that's 1/4, and the 2 means "square it" so that's 1/16
it's the same as 1 over the same number to a positive power. 2 to the power -3 = 1/ 2 cubed = 1/8
They are not! 5-3, for example is not 1/52 nor (1/5)2.
1
(9/2)-1 = 1 / (9/2) = 2/9
Negative 1 over 2
It's the inverse of the number raised to the power. 2 to the power of negative 3 would be 1/8th.1 over 25Improvement(shininggallade):When raising a whole number to a negative power, simply raise 5 to the second power, which is 25, and put a 1 over it. 5^-2=1/25 A more technical definition is to reverse the numerator and denominator and then apply the power. Remember 5 is the same as 5/1, so (5^-2)/1=1/(5^2)=1/25(The symbol for "to the power of" is "^" just to let you know.)
