Answer:
2. 10
3. D. 1 for all n
Step-by-step explanation:
2. The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
a^b = 1/a^-b

![\dfrac{4^8}{(4^2)^{-3}}\div 4^4=\dfrac{4^8}{4^{-6}\cdot4^4}=\dfrac{4^8}{4^{-2}}\\\\=4^8\cdot4^2=4^{10}](https://tex.z-dn.net/?f=%5Cdfrac%7B4%5E8%7D%7B%284%5E2%29%5E%7B-3%7D%7D%5Cdiv%204%5E4%3D%5Cdfrac%7B4%5E8%7D%7B4%5E%7B-6%7D%5Ccdot4%5E4%7D%3D%5Cdfrac%7B4%5E8%7D%7B4%5E%7B-2%7D%7D%5C%5C%5C%5C%3D4%5E8%5Ccdot4%5E2%3D4%5E%7B10%7D)
The value of n is 10.

3. Using the above rules of exponents, the expression simplifies to ...
6^(-n+n) = 6^0 = 1
The value is 1 for any n.

Notice that in the first table, every time we increase x by 1, y consistently decreases by 2. This characterizes a linear function.
Answer:
It is not a right triangles because 15^2 + 13^2 is NOT EQUAL to 19^2
let x, y, and z be the angles inside the triangle.
Law of cosines says:
19^2 = 13^2 + 15^2 - 2(13)(15)cos x
361 = 169 + 225 - 390 cos x
-33 = -390 cos x
-33/-390 = cos x
11/130 = cos x
x = inverse cosine (11/130)
= 85.14609471338569.....
Per law of sines:
sin x/19 = sin y / 13
(13/19)sinx = sin y
inverse_sine ( (13/19) sin x) = y
y = 42.9810733896016548....
Per law of sines
sin x/19 = sin z / 15
z = inverse_sine( (15/19) sin x)
= 51.8728352950227805....
So it is an acute triangle and yes, these angles add up to 180
