Prime Divisors## If it asks for just "how many

Thanks!

## Good question. The word

Good question. The word "different" implies "unique."

## Hi Brent,

So if the question asked for how many prime factors does 8500 has, is the answer 6 ?

## I don't think the test-makers

I don't think the test-makers would ask that question. It seems too ambiguous to me.

## Dear Sir

If a is a repeating decimal and k • a is a terminating decimal, which of the following is a possible value of k?

2

3 correct

4

5

Please help me to solve this problem.

## Choose some nice numbers that

Choose some nice numbers that meet the given conditions.

One repeating decimal that comes to mind is 0.33333... (this repeating decimal is equal to 1/3)

So, let's say a = 0.33333...

If we multiply a by 3, we get 1, which is a terminating decimal.

So, if k = 3, then both conditions are met (a is a repeating decimal and ka is a terminating decimal)

## Thank you sir.

## Hi Brent! Could you explain

Why is E not the right answer?
