7^{2x+3}*49=7^{4x}

7^{2 x + 3} \cdot 49 = 7^{4 x}

x = \frac{5}{2}

Decimal Notation

x = 2.5

Solution steps

7^{2 x + 3} \cdot 49 = 7^{4 x}

Apply exponent rules

2 x + 5 = 4 x

Solve

2 x + 5 = 4 x : x = \frac{5}{2}

x = \frac{5}{2}

5 = (2.82)^{t}

\frac{4 e ^{3 x} - 5}{e ^{3 x} - 1} = 3

350000 = 400 \cdot (1 - e^{- 0.15 t})

3^{x} + 1 = 3^{5}

3^{x^{2} + x} = 9
