=7x-x^2>8
0=7x-x^2-8
0= -x^2 + 7x -8
0=(x^2 + 8x)-(x - 8)
0=x(x + 8)-1(x +8)
0=(x-1) 0=(x+8)

Expression equivalent to $(3b)^{\frac{2}{d}}$ is $(\sqrt[d]{3b})^2$

Option D is correct.

Step-by-step explanation:

We need to find equivalent expression of: $(3b)^{\frac{2}{d}}$

Solving:

We know that $\frac{1}{d}= \sqrt[d]{}$

So, the expression will become:

$(3b)^{\frac{2}{d}}$

$=(\sqrt[d]{3b})^2$

So, expression equivalent to $(3b)^{\frac{2}{d}}$ is $(\sqrt[d]{3b})^2$

Option D is correct.
