Question

Answer 1

\(x=\left(\dfrac{7}{4}\right)^2\)

Answer 2

$x.(\dfrac{7}{4})^6=(\dfrac{7}{4})^8$

$\Rightarrow x=(\dfrac{7}{4})^8:(\dfrac{7}{4})^6=(\dfrac{7}{4})^{8-6}=(\dfrac{7}{4})^2=\dfrac{49}{16}$

Answer 3

\(x.\left(\dfrac{7}{4}\right)^6=\left(\dfrac{7}{4}\right)^8\)

\(x=\dfrac{7}{4}^{\left(8-6\right)}\)

\(x=\left(\dfrac{7}{4}\right)^2\)

\(x=\dfrac{49}{16}=3,0625\)
