Question

can the number 6^n, n being
a natural number,
end
with the digit 5? Give reasons.​

Answer 1

Answer:

NO

Step-by-step explanation:

6ⁿ, where n is a natural no.

When we say 6ⁿ, we multiply 6 n times. however, how many ever times 6 is multiplied, the last digit will always be 6. Example:

• 6¹ = 6
• 6² = 36
• 6³ = 216

and so on....

Answer 2

Answer:

No

Step-by-step explanation:

6^1=6

6^2=36

6^3=216

so 6^n will not end with 5
