ASSERTION (A): 12^n ends with digit zero, where n is a natural number REASON (R): Any number ends with digit zero, if it's prime factorisation is of the form 2 Amx5an, where m and n are whole numbers.
Answers
Answer:
correct option is ( D )
- Asseration ( A ) is false but reason ( R ) is true
Mark me as brainiest.
Given :
ASSERTION (A): 12ⁿ ends with digit zero, where n is a natural number
REASON (R): Any number ends with digit zero, if it's prime factorisation is of the form 2^mx5ⁿ, where m and n are whole numbers.
To Find : True or false
Solution:
ASSERTION (A): 12ⁿ ends with digit zero, where n is a natural number
INCORRECT
as 12¹ = 12 ends with 2 and not zero
Also a number ending with 2 raised to natural number can ens with
2 , 4 , 8 , 6 only
REASON (R): Any number ends with digit zero, if it's prime factorisation is of the form 2^mx5ⁿ, where m and n are whole numbers.
Zero is a whole number if
any of the m and n is zero
then 2^mx5ⁿ does not ends with 0
Hence INCORRECT
if m and n are natural numbers then its true
Hence Reason and assertion both are Incorrect
