In the expansion of (3a + 4b)8, which of the following are possible variable terms? explain your reasoning. a2b3; a5b3; ab8; b8; a4b4; a8; ab7; a6b5 !

We have to find the expansion of

We will use binomial expansion to expand the given expression, which states that the expression is expanded as :

Now expanding we get,

So, the variables are , , ,

d

step-by-step explanation:

d

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
