Question

Which of the following could be the first step in solving the equation below?4x = 17O A. log 4* = log 17OB...4-2.17C. log 4* = 17D. 44* = 477

Answer 1

In the given equation the vraible x is in exponent with 4 at base. So to solve this equation we takr log on both side of equation, as

$\log (4^x)=\log 17$

Further we simplify the expression y using logarthimic property.

Thus first step for solving the equation is taking log on both side. So answer is,

$\log 4^x=\log 17$

Option A is correct.
