Answer 1

Answer:

see explanation

Step-by-step explanation:

Using the rules of logarithms

• log x + log y = log xy

• log x - log y = log ($\frac{x}{y}$ )

• log$x^{n}$ = n log x

(a)

$log_{7}$ 9 + $log_{7}$ 2 = $log_{7}$ (9 × 2) = $log_{7}$ 18

(b)

$log_{8}$ 7 - $log_{8}$ 11 = $log_{8}$ $\frac{7}{11}$

               ↑ required value

(c)

2$log_{9}$ 2 = $log_{9}$ 2² = $log_{9}$ 4
