\log\left(\frac{10}{y}\right) = \log(10) - \log(y)

The general rule is

\log\left(\frac{A}{B}\right) = \log(A) - \log(B)

Other log rules are

\log(AB) = \log(A) + \log(B)

B\log(A) = \log(A^B)

Approximate: log5 4/7
Evgesh-ka [11]
   Properties of Logs

logb(x/y) = log<span>bx</span> - log<span>by</span>.

therefore

log5 (4/7)= log5 (4)- log5 (7)

<span>Solve log 5 (4) and log 5 (7)  with the base change of the logarithm</span>

<span>log 5 4 = log 4 / log 5 </span>

 Use the calculator: 

<span> <span>log 5 4 =0.8613531161 </span></span>

 log 5 7 = log 7 / log 5 

<span>log 5 7 =1.2090619551</span>

<span>log5 (4/7)= log5 (4)- log5 (7)=-0.347708839</span>

Solve for x: −34x−1=115 .
krek1111 [17]

Answer:

x = -\frac{64}{45}

Step-by-step explanation:

-\frac{3}{4}x - 1 = \frac{1}{15}

add 1 to both sides:

-\frac{3}{4}x = \frac{16}{15}

multiply both sides by 4:

-3x = \frac{64}{15}

divide both sides by -3:

x = -\frac{64}{45}
