Question

\(7^{\frac{1}{2}x-5=343}\)

Answer 1

\(7^{\frac{1}{2}x-5}=343\)

\(7^{\frac{1}{2}x-5}=7^3\)

\(\frac{1}{2}x-5=3\)

\(\frac{1}{2}x=3+5\)

\(\frac{1}{2}x=8\)

\(x=8:\frac{1}{2}\)

\(x=16\)

Answer 2

\(7^{\frac{1}{2}x-5}=343\)

=>\(7^{\frac{1}{2}x-5}=7^3\)

=> \(\frac{1}{2}x-5=3\)

=> \(x=16\)

Answer 3

7 X \(\frac{1}{2}\)hay 7\(\frac{1}{2}\)
