Question

Find the unit digit of the expression. 36^500×55^200×224^160​

Answer 1

Answer:

zero

Step-by-step explanation:

Since the multipliers are:

a number ending with 5 and 2 even numbers,

the last digit of their product (5*2=10)

is the last digit of the expression

which is a unit digit

and it equals to zero

Answer 2

Answer:

0

Explanation:

Since we need the units digit, we remove tens and hundreds digits.

36^500 × 55^200 × 224^160

= 6^500 × 5^200 × 4^160

= 6 × 5 × 6

= 180

Hence, the units digit of the expression is 0.
