Question

What is the product? (4x) (-3x 8) (-7x²)

Answer 1

The product of the expression is $84 x^{11}$

Explanation:

The expression is $(4 x)(-3 x ^8)\left(-7 x^{2}\right)$

Let us simplify the expression by multiplying the first two terms.

Thus, we have,

$[(4 x)(-3 x ^8)]\left(-7 x^{2}\right)$

First, multiplying the coefficients, we get, $4(-3)=-12$

Since, the base x is common for both the terms, we can add the exponent.

Thus, we get, $x\left(x^{8}\right)=x^{1+8}=x^{9}$

Thus, the simplification of the first two terms, we have,

$(-12x^9)(-7x^{2} )$

Similarly, we shall multiply the terms $(-12x^9)(-7x^{2} )$, we get,

Multiplying the coefficients, we have, $-12(-7)=84$

Adding the exponents, we have, $x^9\left(x^{2}\right)=x^{9+2}=x^{11}$

Thus, this gives $84 x^{11}$

Hence, the product of the expression is $84 x^{11}$
