Question 165083
I'm assuming that you mean {{{sqrt(a-1)-5 = 1}}}??? Be careful to place your parenthesis in the right spot.



{{{sqrt(a-1)-5 = 1}}} Start with the given equation.



{{{sqrt(a-1) = 1+5}}} Add 5 to both sides.



{{{sqrt(a-1) = 6}}} Add.



{{{a-1 = 6^2}}} Square both sides to eliminate the square root.



{{{a-1 = 36}}} Square 6 to get 36.



{{{a=36+1}}} Add {{{1}}} to both sides.



{{{a=37}}} Combine like terms on the right side.

Answer:


So the answer is {{{a=37}}}
