Jada explains how she finds 15⋅23: “I know that ten 23's is 230, so five 23's will be half of 230, which is 115. 15 is 10 plus 5, so 15⋅23 is 230 plus 115, which is 345.” Do you agree with Jada? Explain.

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.
