20*log_{10}(x)=7

20 \cdot lo g_{10} (x) = 7

x = 1 0^{\frac{7}{20}}

Decimal Notation

x = 2.23872 \dots

Solution steps

20 lo g_{10} (x) = 7

Divide both sides by

20

lo g_{10} (x) = \frac{7}{20}

Apply log rules

x = 1 0^{\frac{7}{20}}

Verify Solutions:

x = 1 0^{\frac{7}{20}}

True

The solution is

x = 1 0^{\frac{7}{20}}

lo g_{10} (x + 5) + lo g_{10} (2 x) = 2

2 lo g_{x} (125) = 6

lo g_{3} (x^{2} + x) = lo g_{3} (4 x)

7 = 11.2 + lo g_{10} (x)

lo g_{3} (x^{3}) = lo g_{9} (27)
