Slove logbase 5 (5x +9) = logbase 5 6x

Logs are the same so

5x+9=6x
Subtract 5x
9= X

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
