log_{2}(2x+5)=3

lo g_{2} (2 x + 5) = 3

x = \frac{3}{2}

Decimal Notation

x = 1.5

Solution steps

lo g_{2} (2 x + 5) = 3

Apply log rules

2 x + 5 = 8

Solve

2 x + 5 = 8 : x = \frac{3}{2}

x = \frac{3}{2}

ln (x) + ln (7 x + 1) = 1

lo g_{5} (n^{2} + 20 n) = 3

lo g_{2} (x - 5) = 2 - lo g_{2} (x - 8)

ln (x^{2}) - 0.7 = 0

0.69 = lo g_{10} (x)
