Question

Prove that 5^7 + 5^6 is divisible by 60

Answer 1

Not divisible

Explanation:

5^7 is 78125

5^6 is 15625

15625 + 78125 = 93750

93750/60 = 1562.5

Therefore it is not fully divisible by 60.

Answer 2

I think it is not ?

Explanation:

You get a remainder at the end when you solve it and that's the opposite of what divisible means

"(of a number) capable of being divided by another number without a remainder."
