Answer:
Step-by-step explanation:
when taking the radical of a number its really just a fractioned exponent for example =
This is because in the radical the x has an exponent of 1 and since its the square root the radical is to the 2nd so you take the exponent of the X and put that of the what ever kind of radial you have such as a square root third root fourth root and so on...
in your case you would take X's exponent of 8 and since your taking the cube root would put the 8 over the 3.

<u>Answer:</u>
- The value of c is 2√2 or about 2.8.
<u>Step-by-step explanation:</u>
<u>We can find the hypotenuse (c) with the help of Pythagoras Theorem.</u>
- => c² = 2² + 2²
- => c² = 4 + 4
- => c² = 8
- => c = √8
- => c = √2 x 2 x 2
- => c = 2√2
<u>If you want further simplification, seek for explanation below.</u>
- => c = 2√2
- => c = 2 x √2
- => c = 2 x 1.414
- => c = 2.828 = 2.8 (Estimated)
Hence, <u>the value of c is 2√2 or about 2.8.</u>

Answer:
The positive graph is on the points (-5,-4) and (2,5)
And, negative would be (-4,2)
Step-by-step explanation:
As it seems that fgraph shows positive in the case when it is over x-axis, and negative when it is below y-axis
As on the interval (-1,5)
The graph is below x-axis i.e. on (-1,2)
And, over x-axis i.e. on (2,5)
At this point Lonzell’s is not correct
As on the interval (-5,-1)
The graph is below x-axis i.e. on (-4,-1)
And, over x-axis i.e. on (-5,4)
At this point Lonzell’s is not correct
So,
The positive graph is on the points (-5,-4) and (2,5)
And, negative would be (-4,2)
