3^{x} \cdot 5^{x - 1} = 10125

x = \frac{ln ( 10125 ) + ln ( 5 )}{ln ( 15 )}

Decimal Notation

x = 4

Solution steps

3^{x} \cdot 5^{x - 1} = 10125

Apply exponent rules

(x - 1 + 1 + lo g_{3} (5) (x - 1)) ln (3) = ln (10125)

Solve

(x - 1 + 1 + lo g_{3} (5) (x - 1)) ln (3) = ln (10125) : x = \frac{ln ( 10125 ) + ln ( 5 )}{ln ( 15 )}

x = \frac{ln ( 10125 ) + ln ( 5 )}{ln ( 15 )}

4 e^{3 x - 2} = 244

3^{3 x} = 3^{2 x - 4}

8^{x} = 5

2^{x + 1} = 9

3 \cdot 2^{x} = 24
