2 5^{a - 3} = 125

a = \frac{15}{4}

Decimal Notation

a = 3.75

Solution steps

2 5^{a - 3} = 125

Apply exponent rules

2 (a - 3) = \frac{3}{2}

2 (a - 3) = \frac{3}{2} : a = \frac{15}{4}

a = \frac{15}{4}

5 (5^{2 x}) + 14 (5^{x}) - 3 = 0

2 = 1.062 5^{t}

2^{x} = 2.6

3^{x} = 343

e^{x + 6} = \frac{1}{e}
