Solve and check your solution(s). If the equation has no real solution, so state.
-$( 4 x + 5 ) ^ { 1 / 2 } = 4$
A)4
B)20
C) $- \frac { 5 } { 4 }$
D) $\frac { 11 } { 4 }$

Question

Quizplus · Accepted Answer

To solve the equation $(4x + 5)^{1/2} = 4$, we first square both sides to eliminate the square root, resulting in $4x + 5 = 16$. Subtracting 5 from both sides gives $4x = 11$, and dividing by 4 yields $x = \frac{11}{4}$.

Solve and Check Your Solution(s) (4x+5)1/2=4( 4 x + 5 ) ^ { 1 / 2 } = 4(4x+5)1/2=4
