Question

plz answer this with solution
it is of class 10
chapter 1​

Answer 1

Answer:

if 4n will end with digit 0

then it must be a factor of 5and 2

but here we can see that

4n=(2*2)n

here is only one factor 2 not 5

hence, the no. 4n will not end with digit 0 because it doesn't have 5 as a factor.

hope this answer useful to you

Answer 2

Factors of 4=2

Hence the no. which ends with digit zero should have factor 2*5 but 4^n doesn't have 5 as a factor. Thus it can't be end with digit zero.
