Question

Show the steps to your solution.Find the value of x in the equation 5^x=1/125

Answer 1

5^x = 1 / 5^3

5^x * 5^3 = 1

5^x * 5^3 = 5^0

x + 3 = 0

x = -3

Answer 2

\[x^{5} = {1 \over 125}\]\[x = \sqrt[5]{1 \over 125} = ({1 \over 125})^{1/5}\]\[x = {1 \over 5}\]

Answer 3

I don't think you can write 5^x like x^5!

Answer 4

oh my bad, misread it
