Question

Find value of log 128 base to 8

Answer 1

Answer:

Log8128=Log(128) ÷ Log(8)

Log(128)= 2.10720996965

Log(8)=0.903089986992

Log8128=2.10720996965 ÷ 0.903089986992

Ans=2.33333333333

Answer 2

$\displaystyle \sf{ log_{8}(128) } = \frac{7}{3}$

Given :

$\displaystyle \sf{ log_{8}(128) }$

To find :

The value of the expression

Solution :

LStep 1 of 2 :

Write down the given expression

The given expression is

$\displaystyle \sf{ log_{8}(128) }$

Step 2 of 2 :

The value of the expression

$\displaystyle \sf{ log_{8}(128) }$

$\displaystyle \sf{ = \frac{log \: 128}{log \: 8} }$

$\displaystyle \sf{ = \frac{log \: {2}^{7} }{log \: {2}^{3} } }$

$\displaystyle \sf{ = \frac{7 \: log \: 2 }{3 \: log \: 2} }$

$\displaystyle \sf{ = \frac{7 }{3 } }$
