Question

Simplify: (4x)(-x^2)(5x^3)

Answer 1

Answer:

-20 x^6

Step-by-step explanation:

(4x)(-x^2)(5x^3)

Multiply the numbers

4*-1 *5 = -20

Add the exponents

x^1 * x^2 * x^3

x^(1+2+3)

x^6

Multiply back together

-20 x^6

Answer 2

Answer:

The answer is

$- 20 {x}^{6}$

Step-by-step explanation:

(4x )( - x²)(5x³)

Expand the terms

That's

-4x³( 5x³)

Next multiply the numbers

That's

- 20( x³)(x³)

Using the rules of indices multiply the x's in the expression

That's

${a}^{x} \times {a}^{x} = {a}^{y + y}$

So we have

${x}^{3} \times {x}^{3} = {x}^{3 + 3} = {x}^{6}$

We have the final answer as

$- 20 {x}^{6}$
