Answer 1

Step-by-step explanation:

Solutions:-

a)

Given that

log 10 (100)

=> log 10 (10)^2

We know that

log a^m = m log a

=> 2 log 10 (10)

We know that

log a (a) = 1

=> 2×1

=> 2

a)----->(iii)

b)

A set having no elements is called an empty or void or null set.

Number of elements in an empty set is 0

b)------> (i)

c)

Given numbers are 17 and 23

17=1×17

23=1×23

HCF=1

Since they are co primes

c)------> (ii)

Answer:-

a)----->(iii)

b)------> (i)

c)------> (ii)

Option - D

Used formulae:-

• log a^m = m log a

• log a (a) = 1

• A set having no elements is called an empty or void or null set.

• The HCF of the co primes is 1 and the LCM is the product of the numbers
