Question

if x=m^3 and y=2n^2, write the following expression in terms of m and n, (2xy^3)^2

Answer 1

wherever there is an x, replace it with m^3, wherever there is a y, replace it with 2n^2

Answer 2

what do I do if there is already an exponent?

Answer 3

powers to the power of something else, just means multiply the powers together.

so ^2 to the power of 3 = ^2x3 = ^6

Answer 4

oh okay would this be right (2m^32n^6)^2

Answer 5

yeah, looks good to me.

Answer 6

okay thanks!:)
