Question

Fill in the missing values to make the equations true.(a) log, 7 + log2 5 = log2음Х8(b) log, 8 - log, I = log,7(c) log, 4 = 2log, I

Answer 1

(a).

Simplify the expression to obtain the value at missing place.

$\begin{gathered} \log _27+\log _25=\log _2(7\cdot5) \\ =\log _235 \end{gathered}$

Blank space: 35

(B).

Simplify the expression to obtain the value of missing place.

$\log _9(\frac{8}{7})=\log _98-\log _97$

Blank space : 7

(C)

Simplify the expression to obtain the value at missing place.

$\begin{gathered} \log _74=\log _7(2)^2 \\ =2\log _72 \end{gathered}$

Blank space: 2
