simplify 4log_{10}(x)-1/2 log_{10}(y)

simplify

4 lo g_{10} (x) - \frac{1}{2} lo g_{10} (y)

lo g_{10} (\frac{x ^{4} y}{y})

Solution steps

4 lo g_{10} (x) - \frac{1}{2} lo g_{10} (y)

Apply log rule:

a lo g_{c} (b) = lo g_{c} (b^{a})

4 lo g_{10} (x) = lo g_{10} (x^{4})

= lo g_{10} (x^{4}) - \frac{1}{2} lo g_{10} (y)

Apply log rule:

a lo g_{c} (b) = lo g_{c} (b^{a})

\frac{1}{2} lo g_{10} (y) = lo g_{10} (y^{\frac{1}{2}})

= lo g_{10} (x^{4}) - lo g_{10} (y^{\frac{1}{2}})

Apply log rule:

lo g_{c} (a) - lo g_{c} (b) = lo g_{c} (\frac{a}{b})

lo g_{10} (x^{4}) - lo g_{10} (y^{\frac{1}{2}}) = lo g_{10} (\frac{x ^{4}}{y ^{\frac{1}{2}}})

= lo g_{10} (\frac{x ^{4}}{y ^{\frac{1}{2}}})

Simplify

\frac{x ^{4}}{y ^{\frac{1}{2}}} : \frac{x ^{4} y}{y}

= lo g_{10} (\frac{x ^{4} y}{y})

ln (5) + ln (7)

ln (\frac{100}{40})

ln (\frac{95 x 1 0 ^{12} ( 2.5 )}{1 0 ^{- 3}})

500 + 47 ln (112) - 47 ln (212)

ln (1.7708) + 0.6 \cdot ln (1.275)
