How Do You Solve Log?

Question

I don't know how to solve this. Can you explain to me how this equation works?

log_{5 (1)}

Answer 1

log to the base 5 of 1 is whatever exponent you need to put over 5 to equal 1

log5(1) = x

5^x = 1

any number raised to the zero power = 1

5^0 = 1

x=0

log5(1) = 0
