Match the base to the corresponding height. Base (b) Height (h) b h 109%7 b b h

The first two math together, then the second base goes to the third height, and the third base goes to the second height, hope this helps!!

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.
