simplify (7^n+7^n-1)/(7^n+1-7^n)

simplify

\frac{7 ^{n} + 7 ^{n} - 1}{7 ^{n} + 1 - 7 ^{n}}

2 \cdot 7^{n} - 1

Solution steps

\frac{7 ^{n} + 7 ^{n} - 1}{7 ^{n} + 1 - 7 ^{n}}

Simplify

\frac{7 ^{n} + 7 ^{n} - 1}{7 ^{n} + 1 - 7 ^{n}} : \frac{2 \cdot 7 ^{n} - 1}{1}

= \frac{2 \cdot 7 ^{n} - 1}{1}

Apply the fraction rule:

\frac{a}{1} = a

= 2 \cdot 7^{n} - 1
