Solve each equation for the given variable. Use inverse operations to solve each equation. X - 5 = 10

X = 15

Inverse operations would be + 5 to the -5 which cancels that out, & adding 5 to the 15 which gives you 15

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.
