Simplify. Rewrite the expression in the form 7^n7 n 7, start superscript, n, end superscript. \left(7^3\right)^{3}=(7 3 ) 3 =left parenthesis, 7, cubed, right parenthesis, cubed, equals

Step-by-step explanation:

We need to write the given expression in the form of and the expression is .

The property is :

We have, x = 7, n = m = 3

So,

Therefore, the value of n is 9.

because they could drop even lower..

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°
