Question

Simplify (3a²b²)²+(ab)²​

Answer 1

Answer:

$a^{2} b^{2}$ (9$a^{2} b^{2}$ + 1)

Step-by-step explanation:

simplify (3a²b²)²+(ab)²​; for the first term, square the 3 and multiply the exponents by 2, also multiply the exponents by 2 in the second term

$9a^{4} b^{4} + a^{2} b^{2}$ ; factor out $a^{2} b^{2}$

$a^{2} b^{2}$ (9$a^{2} b^{2}$ + 1)

Answer 2

(3a^2b^2) + (ab)^2 = (3a^2b^2) + (a^2b^2)
= 4a^2b^2
