`(5475 xx 34750)/(2413)`

This can be solved by taking log first and then after simplifying it taking the anti-log of it.

`log((5475 xx 34750)/(2413))`

This can be simplified into,

`log((5.475 xx 1000 xx 3.475 xx 10000)/(2.413 xx 1000))`

`log((5.475 xx 3.475 xx 10000)/(2.413))`

By applying logarithm rules,

`log((5.475 xx 3.475 xx 10000)/(2.413)) = 0.7383841+0.5409548+4 - 0.3825573`

`log((5475 xx 34750)/(2413)) = 4 + 0.8967816`

Taking the anti-log,

`(5475 xx 34750)/(2413) = 7.8846 xx 10000`

`(5475 xx 34750)/(2413) = 78846`

 

Therefore the answer of `(5475 xx 34750)/(2413)` using log tables is 78846.


The answer using calculator is 78846.353
