Question

show that 9 power n never ends with 0​

Answer 1

Answer:

Step-by-step explanation:

9^n will never end with zero because,

If we factorise 9 we get (3)(3)

A number with power n ends with zero have at least one 2 and one 5 in its factor

And in case of 9 we do not have 2 and 5 so 9 ^n can't be end with zero

Answer 2

9power n will not end with digit 0.

If we factorise the 9, we get the two factors [3][3].

Bt if a digit ends with 0 then it must have factored 2 and 5.

bt 9 do not have factore 2 and 5.

so 9 will never end with digit 0
