Q1:

Quick Answer:

B) x = log↓a(N)

Explanation:

Let's take an example of 10² = 100.

A) Applying a=log↓x(N), it would be

10 = log↓2(100)

10 = 6.643.. which is not true.

B) Applying x = log↓a(N), it would be

2 = log↓10(100)

2 = 2, which is true.

C) Cannot apply N = log, since log cannot be

written solely. So, it cannot be true.

D) Applying N= log↓x(a), it would be

100 = log↓2(10)

100 = 3.3219.., which is not true.

Q2:

Quick Answer:

C) log3 + log5

Explanation:

Using the property log(a × b) = loga + logb, log15 can be written as log(3 × 5) => log3 + log5.
