Simplify using exponent rules (x^8)^3

x^24

Step-by-step explanation:

according to exponent rules:

(x^a)^b = x^(a*b)

so...

(x^8)^3 = x^(8*3) = x^24

hope this helps:)

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
