What is the digit in the unit's (1's) place in the product of 17^60*23^60?

You have to calculate digit at only unit's place. So, you can write them as

7^60 * 3^60

Now, there you should know about CYCLICITY (it means the power after which a number shows same unit digit)

cyclicity for both 3 & 7 is 4

Now, you have to divide powers by 4 and need to focus on remainder. It would become 0 as the power is 60 here.

so, 1*1 =1

1 will be in unit place.

NICE QUESTION!!!

DID YOU UNDERSTAND??

s + (a + 178) = 2000

step-by-step explanation:

2000 - 178 = 1822

1822 / 2 = 911

911 + 178 = 1089

1089 + 911 = 2000

abha = 1089

shane = 911
