Solve 10 ax + 11 ax = 12ax +45 for x. Assume a ≠0. A. x= 5a
B. X= 5/a
c. x = 1/9a
D. x = 9a

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.
