The rule for multiplying similar bases with exponents:

(a^b)(a^c)=a^(b+c)

In this case we have:

(5^-2)(5^-1)

5^(-2-1)

5^(-3)

The rule for negative exponents:

a^(-b)=1/(a^b)

So in this case:

5^(-3) is equal to 

1/(5^3)

1/125

Answer:

1/125

Step-by-step explanation:

In M a t h w a y, this is the answer ya get when the expression's simplified. Hope this helps!
