Which equations are correct?

Leno4ka [110]

9514 1404 393

Answer:

C, D

Step-by-step explanation:

The applicable rules of exponents are ...

(a^b)(a^c) = a^(b+c)

The correct equations are the last two.

For the first two, the appropriate products are ...

$4c^4(3c^2)=4\cdot3c^{4+2}=12c^6\\\\3b^3(a^2b^4)=3a^2b^{3+4}=3a^2b^7$
