Question

5. Solve the equation. (4x+10)^1/4 = (9+7x)^1/4

Answer 1

Answer:

1/3

Step-by-step explanation:

$\sqrt[4]{4x+10}$ = 4x+10 ^1/4

$\sqrt[4]{9+7x}$= 9+7x^1/4

Since they are under the same root, you can combine them under the root.

Then you change the +/- sign of one side of the equation to move to the other side of the equation.

To get....$\sqrt[4]{-3x+1}$=0

^4 both sides to get..

-3x+1=0

Move 1 to the other side...

-3x=-1

divide both sides by -3

x=1/3
