The largest perfect square factor of 252 is

18

Step-by-step explanation:

252 is a composite number. The exponents in the prime factorization are 2, 2, and 1. Adding one to each and multiplying we get (2 + 1)(2 + 1)(1 + 1) = 3 x 3 x 2 = 18. Therefore 252 has 18 factors.

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
