Question

check wether the number 15n, where n is a natural number,and with the digit 0, justify your answer

Answer 1

when n=1
15^1=15
when n=2
15^2=225
when n=3
15^3=3375
and so on......
hence 15^n donot ends with digit zero

Answer 2

to end with digit 0 the no. must have 2and 5 as its factor with any natural no. power of 2 and 5.
Here, 15 = 3×5
therefore, if n has 2 as its factor then it can end with 0 otherwise it will not.
