Question

add the polynomials.
(4a^4b^+6ab)+(ab-4a^4b^4)

Answer 1

you can add things like x^2+x^2=2x^2
Things with the same thing raised to the exponent can be added

Answer 2

did you mean:\[ (4a ^{4}b ^{4}+6ab) +(ab - 4a ^{4}b ^{4}) \]
if so result is 7ab

Answer 3

how confident are you of that answer?
