Question

How do you evaluate `(x+y)^3` for x=22 and y=5?

Answer 1

See explanation below

Explanation:

You substitute `color(red)(22)` for `x` and `color(blue)(5)` for `y` and the calculate the value:

`(color(red)(x) + color(blue)(y))^3` with substitution becomes:

`(color(red)(22) + color(blue)(5))^3 = 27^3 = 27 xx 27 xx 27 = 729 xx 27 = 19,683`
