If you simplify (3. 3^2x . 1/4. 4^2x. 25. 5^3x= 6. 2^2x. 3^3x. 5^2x) this can be written as 4^x . 5^x=a/b. Express a/b in simplest form

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.
