Answer:
2n+8
Step-by-step explanation:
10. 6
11. 13
12. 504
13. 2
14. 162
15. 2 gal
16. 8 at
15. 220 mm
16. 8 km
15. 9 m
16. 200 cm
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.
Answer:
7^2
3^3
Step-by-step explanation:
Exponents signify how many times the base is multiples by itself. In the case of 7x7, 7 is the base and it is being multiplied by twice itself, resulting in an answer of 7^2
Answer: The answer is B
Step-by-step explanation: Because x=6 and y=6 = 12
..y equal twice the times we have right now..... and there is a lot of solutions to equal 12...
