<span>The sum of 5 times a number and -2, added to nine times a number.
.
Looking at the first part:
The sum of '5 times a number' and '-2'
we get
5x + (-2)
or
5x - 2
.
The above is then "added to nine times a number" to get:
5x - 2 + 9x
Combining x's we get:
14x - 2

<span>Take it piece by piece:
5 times a number, rewrite as 5x
plus -2, nothing to rewrite there, that's already simplified,
added to nine times a number, rewrite as 9x.
Now, rewrite as an equation:
5x-2+9x = (See, it already looks better!)
Now combine like terms:
5x + 9x -2= 14x - 2</span></span>
We'll use the exponent rule that a^(b+c) = a^b*a^c
to break up 17^16 into 17^(14+2) = 17^14*17^2
That allows us to factor like so
17^16+17^14
17^14*17^2+17^14*1
17^14(17^2 + 1)
Computing 17^14 is a lot more difficult compared to computing 17^2 + 1, assuming you only could use paper and pencil.
Note that 17^2 = 17*17 = 289, so 17^2 + 1 = 289+1 = 290
Because 290 ends in a 0, this means that 5 is a factor
290 = 5*58
This makes 5 to be a factor of the original expression.
----------------
So overall,
17^16+17^14 = 17^14(17^2 + 1) = 17^14*290 = 17^14*5*58 = 5*17^14*58
The stuff "17^14*58" doesn't matter. All we care about is that factor of 5.
Since 5 is a factor, this means that 17^16+17^14 is a multiple of 5, or 17^16+17^14 is divisible by 5.
Phrased another way, 17^16+17^14 all divided over 5 leads to some integer. In this case, the integer would be the result of 17^14*58.
Both of the answers are 50%. your welcome person.
