Question

(6x-8)^(1/2)=-2

Answer 1

x=2

Answer 2

Squaring both the sides,

\[6x - 8 = (-2)^2\]

6x - 8 = 4

6x = 12


Now you can easily find the value of x..
Can you???

Answer 3

no solution

Answer 4

\[\sqrt{a}\geq 0\] for all \(a\) and therefore \(\sqrt{6x-8}\geq 0\) and in particular it cannot be \(-2\)
