An expression that is equivalent to 20x^4

Veronika [31]

An expression that is equivalent to $20x^4$ is 5 $x^{2}$ × 4 $x^{2}$ or 10 $x^{1}$ ×2 $x^{3}$

Step-by-step explanation:

We can write the equivalent expression for the given expression as,

5 $x^{2}$ × 4 $x^{2}$ = 20 $x^{2+2}$ = 20 $x^{4}$

We can add the powers of x as 2+ 2 = 4.

Since the base x is same we can add the powers as per the law of exponents as, $x^{m}$ × $x^{n}$ = $x^{m+n}$

10 $x^{1}$ ×2 $x^{3}$ = 20 $x^{1+3}$ = 20 $x^{4}$

So an expression that is equivalent to $20x^4$ is 5 $x^{2}$ × 4 $x^{2}$ or 10 $x^{1}$ ×2 $x^{3}$
