Assuming simplify then
get rid of parenthasees by assuming that there is a 1 in front of each, so multply by 1 and get rid of partenthasees so
5p^2-3+2p^2-3p^3
add like terms
7p^2-3p^3-3
normally ordered with biggest exponenst to the left from left to right decending
so
-3p^3+7p^2-3
6/7
Hope it helps Love.

Answer:

Step-by-step explanation:
Which expression represents [⁵√(−21)]⁶ in rational exponent form?
Solution:
Rational numbers are numbers which can be expressed as fractions in the form a / b, where a, b are integers and b is not equal to zero.
A rational exponent is an exponent that is a fraction. For example √2 =
.
When expressing a number in rational exponent form, the numerator of the fractional exponent refers to a normal power, but the denominator refers to the root.
![[\sqrt[5]{(-21)}]^6 = (-21)^\frac{6}{5}](https://tex.z-dn.net/?f=%5B%5Csqrt%5B5%5D%7B%28-21%29%7D%5D%5E6%20%20%3D%20%28-21%29%5E%5Cfrac%7B6%7D%7B5%7D)
Answer:
When simplified they all are 1/5
So yes they are proportional
