Question

Complete the steps to evaluate log798, given log72 ≈ 0.356.

Answer 1

Answer: The correct option is C.

Explanation:

The given expression is,

$log_798$

It can be written as,

$log_798=log_7(2\times 49)$

According to the product property of logarithm.

$log_a{xy}=log_ax+log_ay$

Using the product perty of logarithm the given expression can be written as,

$log_798=log_72+log_749$

The value of $log_72\approx 0.356$, so

$log_798=0.356+log_749$

Hence the correct option is C.

Answer 2

-log72+log749 its D
 and the next one is
-log749= (2)
and
the last one 
-log798=2.356
