I’m literally so dumb omg

The expression NOT equivalent to a³b³ is  ⇒ B

Step-by-step explanation:

Let us revise some rules of exponents

let us solve the question

∵ (a²b)(b²a) = a² × a × b × b²

∵ a² × a × b × b² = ×  

∴ a² × a × b × b² = a³ × b³

∴ (a²b)(b²a) = a³b³

∵ have mo multiplication or division operations

∴ We can not add the powers or subtract them

∴  ≠ a³b³

∴ The expression NOT equivalent to a³b³ is

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°

the answer to your question is c.)   volcanoes built the mountains and earthquakes tore them down.
