Find following product:
$ -3 a^2 \times 4 b^4 $

Answer
To multiply algebraic expressions, we can use commutative and associative laws along with the law of indices, $a^m \times a^n=a^{m+n}$ wherever applicable.
We have:
$ -3 a^2 \times 4 b^4 $
$ =(-3 \times 4) \times\left(a^2 \times b^4\right) $
$ =-12 a^2 b^4$
Thus, the answer is $-12 a^2 b^4$
