Answer 1

we need to multiply 65 249times and we observe that 625 is the digit
as we go on multiplying we see 625 is the last three digits coming continuously. please mark as brainlist

Answer 2

65 ^249 is the case.
When 65 has power as 1 last digit is 5.
When 65 has power as 2 last 2 digits are 25.
When 65 has power as 3 last 3 digits are 125.
When 65 has power as 4 last 2 digits are 25.
Again when 65 has power as 5 last 3 digits are 125.

So, We can say that since 249 is odd then last 3 digits are 125. BTW I can say the digits are 25 or 125 because in 65 the last digit is 5 which always follows a pattern.
