Question

Find each of the following products:
(i) $5x^2\times 4x^3$
(ii) $-3a^2\times 4b^4$

Answer 1

(i)Let us simplify the given expression

$5\times x\times x\times 4\times x\times x\times x$
= $5\times 4\times x^{1+1+1+1+1}$
= $20\times x^5$
= $20x^5$

(ii) Let us simplify the given expression
$–3\times a^2\times 4\times b^4$
= $-12\times a^2\times b^4$
= $-12a^2{b}^4$
