Answer:
a = 0
Step-by-step explanation:
The cube root (radical) is equivalent to x^(1/3). When that is divided by x^(1/3), the result is ...
(x^(1/3))/(x^(1/3)) = x^(1/3 -1/3) = x^0
Comparing that to x^a, we find a=0.

The applicable rules of exponents are ...
![\sqrt[n]{x^m}=x^{\frac{m}{n}}\\\\\dfrac{x^a}{x^b}=x^{a-b}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%5Em%7D%3Dx%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D%5C%5C%5C%5C%5Cdfrac%7Bx%5Ea%7D%7Bx%5Eb%7D%3Dx%5E%7Ba-b%7D)
Pretty sure it's D. When you have a fractional exponent, the root number is always on the bottom, while the exponent on the top. Since x and y are not grouped together in a parentheses, we can assume that only "y" is being raised to the 2/9 power. That means "x "will stay out in front and y will be in the 9th root being raised to the 2nd power.
Answer:
175/48
Step-by-step explanation:
Convert 8 6/8 and 2 2/5 to fractions
8 6/8 = 70/8 ; 2 2/5 = 12/5
Now, we have : 70/8 : 12/5
= 70/8 x 5/12
= 70x5/8x12
=350/96
Simplify the fraction, we get 175/48
We have a work problem here. We can use our knowledge on ratio and proportion in order to set up and equation to determine what is being asked. We do as follows:
1 job / 3 hours for both = 1 job / 8 hours for charlie + 1 / x hours for sam alone
Therefore, the equation would be
1/3 = 1/8 + 1/x
8 degrees
It goes from -3 to -2,-1,0,1,2,3,4,5.
