Which of the following expressions are equivalent? justify your reasoning. 4√x3 1 x−1 10√x5•x4•x2 x 1 3 •x 1 3 •x 1 3

don’t know last one sorry

step-by-step explanation:

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q
