125=(1/25)^{y-1}

125 = (\frac{1}{25})^{y - 1}

y = - \frac{1}{2}

Decimal Notation

y = - 0.5

Solution steps

125 = (\frac{1}{25})^{y - 1}

Apply exponent rules

3 = - 2 (y - 1)

Solve

3 = - 2 (y - 1) : y = - \frac{1}{2}

y = - \frac{1}{2}

3 e^{2 x} + 5 = 16 e^{x}

450000 = 200000 (1 + 0.16)^{x}

3 (2^{x + 4}) = 228

2^{5 x + 15} = 3 2^{x + 3}

x^{1 + l o g_{10} (x)} = 100
