Question

which expression is equivalent to x6 – 9?



(x3)2 – 33


(x3)2 – 32


(x3)3 – 32

Answer 1

If you would like to know the equal expression to the x^6 - 9, you can do this using the following steps:

x^6 - 9 = (x^3)^2 - 3^2
(x^3)^2 = x^3 * x^3 = x^6
3^2 = 3 * 3 = 9

The correct result would be (x^3)^2 - 3^2.

Answer 2

Answer:

$(x^{3})^{2} -3^{2}$

Step-by-step explanation:

we have

$x^{6}-9$

we know that

$x^{6}-9=(x^{3})^{2} -3^{2}$

Applying difference of square

$(x^{3})^{2} -3^{2}=(x^{3}+3)(x^{3}-3)$
