1280=(5)4^{(n-1)}

1280 = (5) 4^{(n - 1)}

n = 5

Solution steps

1280 = (5) \cdot 4^{(n - 1)}

Switch sides

5 \cdot 4^{n - 1} = 1280

Divide both sides by

5

4^{n - 1} = 256

Apply exponent rules

n - 1 = 4

Solve

n - 1 = 4 : n = 5

n = 5

3^{x - 5} = 81

\frac{15}{1 + 2 e ^{- 0.5 n}} = 7.5

72 = 2^{n} \cdot 3^{2}

2 = (1.06)^{x}

2^{3 n + 1} = 32
