The Katz family went to the Central Park Zoo. There they saw twice as many monkeys as seals. The number of bears was 1 less than the number of monkeys. There were 3 times as many giraffes as bears. There are 40 animals at the zoo. How many of each animal did the Katzes see?

Ineed with this same question!

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.
