log_{10}(8x)=2

lo g_{10} (8 x) = 2

x = \frac{25}{2}

Decimal Notation

x = 12.5

Solution steps

lo g_{10} (8 x) = 2

Apply log rules

8 x = 100

Solve

8 x = 100 : x = \frac{25}{2}

x = \frac{25}{2}

3 lo g_{10} (x) - 2 lo g_{10} (5 x) = 2

lo g_{10} (x) = 32768

lo g_{10} (k) = - 0.34

ln (x + 4) + ln (x) = ln (3 x + 6)

lo g_{2} (x) + lo g_{2} (x + 3) = \frac{1}{4}
