Answer:
The answer is
[tex] - 20 {x}^{6} [/tex]
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
[tex] {a}^{x} \times {a}^{x} = {a}^{y + y} [/tex]
So we have
[tex] {x}^{3} \times {x}^{3} = {x}^{3 + 3} = {x}^{6} [/tex]
We have the final answer as
[tex] - 20 {x}^{6} [/tex]
Hope this helps you
