Question

check whether 5 to the power n cannot end with digit 2 for any natural no n

Answer 1

Hey there!
Praneeth from Brainly.in here to help.

✦ 5^1=5,
✦ 5^2=25,
✦ 5^3=125
✦ 5^4=625
✦ 5 ^5=3125
✦ 5^n=_5

If we observe for a natural number ' n ', the value of 5^n has a unit's digit as 5
So,5^n ends with 5 only

So, 5^n [5 to the power n ] can't end with 2

hope helped!

Answer 2

Hey friend,

★5¹=5
★5²=25
★5³=125
★5⁴=625
★5^5=3125
★5ⁿ=____5

From above observation, we can say that 5 to the power any number end with 5 and not with 2.

Hence checked.

Hope it helps
