Evaluate each log without a calculator

QUESTION 1

The given logarithmic expression is

We rewrite in the index form to base 4.

This implies that;

We now apply the power rule: .

Recall that logarithm of the base is 1.

QUESTION 2

The given logarithm is;

This is the same as;

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
