When 10b=5( + 2) is solved for c, one equation is c = (25–2)? Which of the following is an equivalent equation to find c?
O C=105-10-5
O C=(106-10-5)
(106-2)2
25
(106-10)
25

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.
