When the exponent is negative, you have to make the number a fraction(1 over the number).
For example:


This gets rid of the negative, but it leaves the exponent

When an exponent is a fraction, it is the square root.
For example:
![x^{\frac{1}{3}} = \sqrt[3]{x}](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%20%3D%20%20%5Csqrt%5B3%5D%7Bx%7D)

![x^{\frac{1}{4}}=\sqrt[4]{x}](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7B1%7D%7B4%7D%7D%3D%5Csqrt%5B4%5D%7Bx%7D)
So...

Answer:
it's C
Step-by-step explanation:
A rational number times a rational number=rational numberan irrational number times a rational number=irrational number
remember, a rational number is a number that can be written as a/b where a and b are integers and b≠0
A is irrational because the pattern doesn't repeatb is irrational because it's a crazy square rootC is irrationalD is not irrational, it is a fraction
answer is D
Answer: yes
Step-by-step explanation:
Answer:
n = 28 degree
Step-by-step explanation:
2n + 17 + 2n - 5 + 2n = 180 degree (sum of interior angles of a triangle)
6n +12 = 180
6n = 180 - 12
n = 168/6
n = 28 degree
