843219 to the power of 100 is multiplied out,what is its units digit?
kondaur [170]

Answer:

1

Step-by-step explanation:

We will consider only the last digit multiplication and the pattern.

When we multiply 843,219 with 843,219, we have

9 * 9 = 81 [1 is important]

1 * 9 = 9

9 * 9 = 81 [1 is important]

So when we multiply them out with each other, we have a pattern of

9, 1, 9, 1 ... goes on

So if we multiply 100 times, what will be the last digit of the series 9, 1, 9, 1 .... it will be 1

hence, last digit is 1

All you have to do is multiply the top # and bottom # in the fraction by 5.

5*5 = 25
5*12 = 60

In 5 years, there are 60 months. During that time, a main dish will be on the cover 25 times.
