Answer:
30t - 120t² + 10t³
Step-by-step explanation:
30t + 10t³ - 120t²
In order of degrees of function, t³ > t² > t
So in terms of order of decreasing order, we have to rearrange the equation to
30t - 120t² + 10t³ likewise in terms if increasing degree of function,
10t³ - 120t² + 30t

Answer:
as written: 7x^2
perhaps intended: 7x^4
Step-by-step explanation:
As written, the Order of Operations specifies that the only denominator factor is 3, so the expression is interpreted as ...

___
Sometimes grouping of denominator factors is intended, but parentheses are not written as they should be. If the intention is ...
21x^3/(3x^-1)
then the simplification is ...

_____
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
a^b/a^c = a^(b-c)
