Answer:

7x^2 + 2x - 4

Step-by-step explanation:

First, combine like terms:  Combine 5x^2 and 2x^2, obtaining 7x^2.  Include the 2x term (there is no like term for this one) and combine -10 +  6, obtaining -4.

Then the sum of these two polynomials is

7x^2 + 2x - 4

Note:  Use " ^ " to indicate exponentiation.

Answer:

7x^2+2x-4

Step-by-step explanation:

a standard form is ax+by=c

5x^2 add 2x^2=7x^2 then -2x but when you have a -10 +6 you get -4 giving you the answer of 7x^2 +2x -4

Rewrite 81 as 3 to some power.
NikAS [45]
First, let's find all the factors of 81:

81/3=27
27/3=9
9/3=3
3/1=1

So the factors of 81 are 3,3,3,3, (the numbers by which we divided here).

This means we can write down 81 as 3*3*3*3 or 3^{4} - which is the answer to the question! (three to the power of 4)
