Question

Find product for 5x(4x2)

Answer 1

the answer is 40

Explanation:

5x(4x2)

5x8

40

Answer 2

`20x^3`

Explanation:

To find the product of the expression

`5x(4x^2)`

we must multiply both coefficients 5 and 4, and multiply the variables using the property:

`x^m*x^n=x^(m+n)`⇒ when multiplying a variable with different exponents, these exponents must be added (Note:
`x=x^1`)

So the product will be as follows

`5x(4x^2)=(5*4)(x*x^2)=20(x*x^2)=20x^(1+2)=20x^3`

The answer is
`20x^3`
