9\times 27^x=27

9 \cdot 2 7^{x} = 27

x = \frac{1}{3}

Decimal

x = 0.33333 \dots

Solution steps

9 \cdot 2 7^{x} = 27

Divide both sides by

9

2 7^{x} = 3

Apply exponent rules

3 x = 1

Solve

3 x = 1 : x = \frac{1}{3}

x = \frac{1}{3}

e^{x} - e^{- x} = 5

x, y = e^{x \cdot y + 1}

lo g_{3} (2 7^{3 x + 4}) = - 2

9^{x} + 4 \cdot 3^{x} - 3 = 0

3^{2 x} = 6^{3 x - 1}
