Question

Use factoring to prove that 16⁵+16⁴ is divisible by 17.

Answer 1

16^5 + 16^4 = 16^4(16 + 1) = 16^4(17)

Explanation:

Here, we are to use factoring to show that the given expression is divisible by 17.

That would go as follows;

16^5 + 16^4 = 16^4(16 + 1)

= 17(16^4)

This shows clearly that the expression is divisible by 17
