40

Answer:

[tex]20x^3[/tex]

Step-by-step explanation:

To find the product of the expression

[tex]5x(4x^2)[/tex]

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

[tex]x^m*x^n=x^{m+n}[/tex]⇒ when multiplying a variable with different exponents, these exponents must be added (Note: [tex]x=x^1[/tex])

So the product will be as follows

[tex]5x(4x^2)=(5*4)(x*x^2)=20(x*x^2)=20x^{1+2}=20x^3[/tex]

The answer is [tex]20x^3[/tex]
