A. .8357
B. .8293
C. .8325
D. .8388

Answer 1

Answer is B I believe

Answer 2

Option A)0.8357

Explanation:

Given is a number 6.85 and we are to find log of 6.85 to base 10.

From the table we find that log of 6.85 to base 10 is 0,8357

Hence correct answer is 0,8357

Verify:

From the definition of logrithms,

we can say if
`a^x =b\\log_a b = x`

Using this same concept we can check that

`10^(0.8357) =6.8501\\=6.85`

Hence option A is right
