Question

solve for radical equation. √5x-4=6

Answer 1

√5x-4=6
√5x=6+4
√5x=10
\[x = \frac{10}{\sqrt 5} =\frac{5 \times 2}{\sqrt 5}=\frac{\sqrt 5 \times \sqrt 5 \times 2}{\sqrt 5}\]
\[\rightarrow x =\frac{1 \times \sqrt 5 \times 2}{1}= 2\sqrt 5\]
Thus
\[x=2\sqrt5\] is the solution of this equation
