(7ab+4a2b4)+(a2b4-7ab)

Question

The 2 and 4 are on top of the a and b. (sqare #)

Answer 1

You need to find the like terms, for example, a²b⁴ and 4a²b⁴ are like terms.
You can add them together to make 5a²b⁴.
So
a²b⁴+4a²b⁴=5a²b⁴

Like terms must have the same variables each raised to the same power. We can add like terms by adding the coefficients, as we did above.

Answer 2

ahh so the 7ab cancels because of the -7ab so answer is 5a²b4. I thought it was 4a4b8

Thank you

Answer 3

yes 7 a b - 7 a b = 0
and the answer is
5 a^2 b^4

Answer 4

Your answer is correct.

Answer 5

so its 4a^2b^8?

Answer 6

I mean this is correct:
"ahh so the 7ab cancels because of the -7ab so answer is 5a²b4."

Answer 7

Post it.

Answer 8

"...so answer is 5a²b4"
