x6.x3

x6/x3

(x6)3




​

Answer 1

Answer:

$\dfrac{x^6}{x^3}$  is equal to $x^3$

Step-by-step explanation:

We shall simplify each of the given options using the rules of exponents.

1) $x^6-x^3$ cannot be simplified again.

2) $x^6\times x^3=x^{6+3}=x^9$

3) $\dfrac{x^6}{x^3}=x^{6-3}=x^3$

4) $(x^6)^3=x^{6\times 3}=x^{18}$

So the correct option is $\dfrac{x^6}{x^3}$ .
