Question

What is the solution to the equation? 4√x-4 =3 A. -8 B. 16 C. 85 D. no solution

Answer 1

Answer:

Step-by-step explanation:

4√(x-4) = 3

√(x-4) = 3/4

Square both sides:

x - 4  = 9/16

x = 4 + 9/16

x = 4 9/16.

Answer 2

${\qquad\qquad\huge\underline{{\sf Answer}}}$

Here we go ~

$\qquad \sf \dashrightarrow \: \sqrt[4]{x - 4} = 3$

$\qquad \sf \dashrightarrow \: x - 4 = (3) {}^{4}$

$\qquad \sf \dashrightarrow \: x - 4 = 81$

$\qquad \sf \dashrightarrow \: x = 81 + 4$

$\qquad \sf \dashrightarrow \: x = 85$

So, the correct choice is 85
