Question

(1/aa-3b)(3b+1/2a)(1/4a^2-9b^2

Answer 1

is this a full questions????? what to do with this????

Answer 2

Step-by-step explanation:

(1/2a-3b)(1/2a+3b)(1/2a²+9b²)

=(a+b)(a-b)=a²-b²

=a=1/2a , b=3b

=(a+b)(a-b)=(a²-b²)

=[(1/2a)²-(3b²)]. [1/4a²+9b²]

=[a/4²-9b²] [a/4²+9b²]

=(a/4)²-(9b)²

=a/16⁴-81b⁴. (proved)
