Ok so the answer is
![4 {x}^{2}](https://tex.z-dn.net/?f=4%20%7Bx%7D%5E%7B2%7D%20)
so we multiply numbers that have the same variable
![2 {x}^{3} \: \: \times {2x}^{ - 1} \\ \\](https://tex.z-dn.net/?f=2%20%7Bx%7D%5E%7B3%7D%20%5C%3A%20%5C%3A%20%5Ctimes%20%7B2x%7D%5E%7B%20-%201%7D%20%5C%5C%20%5C%5C%20)
multiply 2 x 2
![2 \times 2 = 4](https://tex.z-dn.net/?f=2%20%5Ctimes%202%20%3D%204)
then multiply the exponents
![x ^{3} \times x ^{ - 1}](https://tex.z-dn.net/?f=x%20%5E%7B3%7D%20%5Ctimes%20x%20%5E%7B%20-%201%7D%20)
multipling like this will look like addition.
![{x}^{3} \times {x}^{ - 1} = {x}^{2}](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B3%7D%20%5Ctimes%20%7Bx%7D%5E%7B%20-%201%7D%20%3D%20%7Bx%7D%5E%7B2%7D%20)
so in other words you could do it like this too
![{x}^{3} + {x}^{ - 1} = {x}^{2}](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B3%7D%20%2B%20%7Bx%7D%5E%7B%20-%201%7D%20%3D%20%7Bx%7D%5E%7B2%7D%20)
now add the exponent with 4
![4 + {x}^{2} = 4x ^{2}](https://tex.z-dn.net/?f=4%20%2B%20%7Bx%7D%5E%7B2%7D%20%3D%204x%20%5E%7B2%7D%20)
now for the last part
![{y}^{3} + {y}^{ - 3} = 0](https://tex.z-dn.net/?f=%20%7By%7D%5E%7B3%7D%20%2B%20%7By%7D%5E%7B%20-%203%7D%20%3D%200)
because -3 and 3 added together make 0
![0 + 4 {x}^{2} = 4 {x}^{2}](https://tex.z-dn.net/?f=0%20%2B%204%20%7Bx%7D%5E%7B2%7D%20%3D%204%20%7Bx%7D%5E%7B2%7D%20)
I hope this help(it looks complicated but it's very easy and I hope I helped you out)
Four below let it go five above give it a shove so the number turns into 2,600
6,975/18 = 387.5 This is how much he makes per week.
387.5/25= $15.50 per hour
Gary makes $15.50 an hour.
