Answer:


5^(-3) in scientific notation would be
8*10^(-3).

Explanation:

An integer to the power of a negative number is equivalent to one over that base to the power of the positive exponent. In this case,
5^(-3) would be
(1)/(5^(3)) or
(1)/(125), which equals 0.008. Scientific notation is a way to express a number in the form of
a * 10^(b) where
a is greater than or equal to 1 but less than 10. We know that 8 would be the value of
a, so all you need to know is the value of
b. Because
10^(-3) is equivalent to 0.001, and multiplied by 8 is equivalent to 0.008, that means
5^(-3) in scientific notation would be
8*10^(-3).
