Answer:
A and C.
Step-by-step explanation:
to get rid of the square root & n, you would have to multiply it by n on both sides of the equation, giving you r^n=a.
also to get rid of the square root & n, you can also multiply both sides of a and r by the exponential fraction with n as the denominator:
![\sqrt[n]{a} =r \\(a)^\frac{1}{n} = r\\a\frac{1}{n} = r](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%7D%20%3Dr%20%5C%5C%28a%29%5E%5Cfrac%7B1%7D%7Bn%7D%20%3D%20r%5C%5Ca%5Cfrac%7B1%7D%7Bn%7D%20%3D%20r)
Answer:
z=-13/7
Step-by-step explanation:
1. Add 3z(7z+5=-8)
2. Subtract 5(7z=-13)
3. Divide 7(z=-13/7)
One of the points is located at (2,-3) the other point is located at (-2,0). If you count the rise it’s 3, the run is 4.

Selection C is appropriate for a fence that extends x feet away from the house and utilizes the full 30 ft width of the house.
If you are moving the decimal point to the left, the exponent is negative. If you move it to the right, the exponent is positive.
There is only one negative exponent here, and it is the first option.
So:
A number is being written in scientific notation. The student moves the decimal point to the left 3 places and A<span>. multiplies by 10^-3.</span>
