Answer:
The final simplification is (32p^-15).
Step-by-step explanation:
Given:
(2p^-3)^5 we have to simplify.
Property to be used:(Power rule)
Power rule states that: ...the exponents were multiplied.
Using power rule.
We have,
⇒
⇒ ...taking exponents individually.
⇒ ...
So our final values are 32p^-15
x = 10
y = 20
7x + 90 + 20 = 180
7x = 70
5x + 2y = 90
50 + 2y = 90
2y = 40
u equals 3.43 because you subtract from both sides.
The answer is <u>option B</u>
