Can someone me solve this ixl problem

The answer is 42 because that is half of 84 and 31 of the muffins were banana which is half of 62

31 plus 62 comes to 93 muffins total.  Thus, 31/93, or 1/3, of the total are banana nut muffins.  If this pattern is repeated, then (1/3)(84), or 28, muffins will be made out of the next 84.

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.
