Answer: 12
Step-by-step explanation:
5 * 12 + 36 = 96
10 * 12 = 120
12 with the exponent of 2 = 144
Add them all and it is 360
the last step is wrong because we multiply the powers in this case we do not subtract them.
we use power subtract in division.
we use power multiplication when we raise to power and the root is power like square root of x

so
![\sqrt[3]{x} = {x}^{ \frac{1}{3} }](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7Bx%7D%20%20%3D%20%20%7Bx%7D%5E%7B%20%5Cfrac%7B1%7D%7B3%7D%20%7D%20)
in our case
this step is wrong
![2x \times \sqrt[3]{ \frac{2}{y} \times \frac{y}{y} }](https://tex.z-dn.net/?f=2x%20%5Ctimes%20%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7B2%7D%7By%7D%20%20%5Ctimes%20%20%5Cfrac%7By%7D%7By%7D%20%7D%20%20)
it should be
![2 x \times \sqrt[3]{ \frac{2}{y} \times \frac{ {y}^{2} }{ {y}^{2} } }](https://tex.z-dn.net/?f=2%20x%20%5Ctimes%20%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7B2%7D%7By%7D%20%20%5Ctimes%20%20%5Cfrac%7B%20%7By%7D%5E%7B2%7D%20%7D%7B%20%7By%7D%5E%7B2%7D%20%7D%20%7D%20)
so we get
![2x \times \sqrt[3]{2 {y}^{2} \times \frac{1}{ {y}^{3} } }](https://tex.z-dn.net/?f=2x%20%5Ctimes%20%20%5Csqrt%5B3%5D%7B2%20%7By%7D%5E%7B2%7D%20%5Ctimes%20%20%5Cfrac%7B1%7D%7B%20%7By%7D%5E%7B3%7D%20%7D%20%20%7D%20)
![= \frac{2x}{y} \times \sqrt[3]{2 {y}^{2} }](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B2x%7D%7By%7D%20%20%5Ctimes%20%20%5Csqrt%5B3%5D%7B2%20%7By%7D%5E%7B2%7D%20%7D%20)
Check the picture below.
notice that the triangle ADH, since the segment AL is an angle bisector, meaning it cuts the angle A in two equal halves, then the triangle ADH is only using half of A.
