1) Which expression is equivalent to 45^-3/45^3

A 45^-1
B 45^0
C 1/45^6
D 45^6

C.

Step-by-step explanation:

Concepts Used:

Simplifying the given expression:

We are given the expression:

According to the rule of negative exponents, 45⁻³ = 1/45³

According to the Power of a Product rule: aⁿ X aᵇ = aⁿ⁺ᵇ

Using the Power rule to further simplify our expression:

Hence, Option C is correct

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°
