Sometimes
1. The radical expression
![\sqrt[n]{}](https://tex.z-dn.net/?f=%20%5Csqrt%5Bn%5D%7B%7D%20)
with even n requires <span>a variable with positive quantity. For example, if you have
![\sqrt[4]{x^3}](https://tex.z-dn.net/?f=%20%5Csqrt%5B4%5D%7Bx%5E3%7D%20)
, then always

2. If you have radical expression
with odd n, ia variable may be arbitrary. For example, for
![\sqrt[7]{x}](https://tex.z-dn.net/?f=%20%5Csqrt%5B7%5D%7Bx%7D%20)
you can consider all real x.
Set up a proportion.100 over 140 is = to x over 100. from there you cross multiply to get 10000=140x. then you divide both sides by 140 and get 71.42857143 and round it. if you are rounding to the nearest whole # it would be 71%
Answer:
c=14•366
14•4 to the nearest tenth
Step-by-step explanation:
using Pythagoras theorem
c^2=a^2+b^2
c^2=7•9^2+12^2
c^2=62•41+144
c^2=206•41
take the square roots of both sides
c=14•3669
14•4 to the nearest tenth
First one should be = to each other the second one I can’t help with and the third one is a>a
Given:
Consider the expression 
simplifies to 
.
To find:
The value of a.
Solution:
We have,
Using distributive property, we get
On comparing the coefficients of 
from both sides, we get
Therefore, the value of a is 6.
