The least common denominator of two fractions is 24.if you add the two denominators, their sum is 14.what are the denominators?

The two denominator would be 6 and 8 because they both = 14 and the lcm of both are 24

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.
