Question

[ 2 . ( x - 1 ) + 6  ] \(^5\) = 1

Answer 1

\(\left[2\left(x-1\right)+6\right]^5=1^5\\ 2\left(x-1\right)+6=1\\ 2\left(x-1\right)=-5\\ x-1=-\dfrac{5}{2}\\ x=-\dfrac{5}{2}+1\\ x=-\dfrac{3}{2}\)

Answer 2

\(\left[2.\left(x-1\right)+6\right]^5=1\)

\(\Rightarrow2\left(x-1\right)+6=1\)

\(\Rightarrow2\left(x-1\right)=-5\)

\(\Rightarrow x-1=-\dfrac{5}{2}\)

\(\Rightarrow x=-\dfrac{3}{2}\)

Answer 3

\(=>2\left(x-1\right)+6=1\)

\(2\left(x-1\right)=-5\)

\(x-1=\dfrac{-5}{2}\)

\(x=\dfrac{-3}{2}\)
