simplify 20-20log_{10}(1.49*1.5)

simplify

20 - 20 lo g_{10} (1.49 \cdot 1.5)

80 - 20 lo g_{10} (2235)

Solution steps

20 - 20 lo g_{10} (1.49 \cdot 1.5)

20 lo g_{10} (1.49 \cdot 1.5) = 20 lo g_{10} (2235) - 60

= 20 - (20 lo g_{10} (2235) - 60)

Expand

- (20 lo g_{10} (2235) - 60) : - 20 lo g_{10} (2235) + 60

= 20 - 20 lo g_{10} (2235) + 60

Add the numbers:

20 + 60 = 80

= 80 - 20 lo g_{10} (2235)

\frac{( ln ( 5 ) - ln ( 3 ) )}{ln ( 2 )}

lo g_{6} (6 x^{3} y^{4})

ln (\frac{sin ( x )}{x ^{2}})

ln (sin (9) x^{3})

ln (m^{2} e^{m x})
