Question

1)Find the value of the monomial –0.125y4 for y=–2 2)Find the value of the monomial. 12x2y for x=–0.3, y= 1/6 3)Represent the following expressions as a power of the number a (a≠0): ((a^2)^-2)^2

Answer 1

Please, use " ^ " to denote exponentiation.

1) Find the value of the monomial –0.125y^4 for y=–2

     Replace y with (-2):         –0.125(-2)y^4
                                         =   -0.125(16) = 2 (answer)
