Question

If x^6=60 and w^10=20, what is x^12×w^-10? A. 36, B. 60, C. 180 or D. 360

Answer 1

Answer:

$x^{12} w^{-10}$

And we can find this rewriting the expression in terms of the info given and we got:

$x^{12} w^{-10} = (x^6)^2 (w^{10})^{-1}$

And replacing we got:

$x^{12} w^{-10} = (60)^2 (20)^{-1}= \frac{60^2}{20}= 180$

And the best option would be:

C. 180

Step-by-step explanation:

For this case we know that:

$x^6, w^{10} = 20$

And we want to find the value for:

$x^{12} w^{-10}$

And we can find this rewriting the expression in terms of the info given and we got:

$x^{12} w^{-10} = (x^6)^2 (w^{10})^{-1}$

And replacing we got:

$x^{12} w^{-10} = (60)^2 (20)^{-1}= \frac{60^2}{20}= 180$

And the best option would be:

C. 180
