Answer 4

so its B? 4x2 and 3x1.

Answer 5

\(\Large \bf \left(3x^{\frac{3}{4}}\right)\left(8x^{\frac{1}{2}}\right)\implies 3\cdot 8\cdot x^{\frac{3}{4}+\frac{1}{2}}\)

Answer 6

but if u add the fractions it wouldnt be a answer

Answer 7

woudln't be an answer? youi mean none of the choices would match?

Answer 8

Answer 12

it is B

Answer 13

3x^3(8x^1) =3x3*8x =3*x^3*8*x =(3*8)*(x^3*x) =24*x^4
=24x^4

Answer 14
