Hello!

Recall that:
is equal to
. Therefore:
![\sqrt[3]{x^{2} } = x^{\frac{2}{3} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%5E%7B2%7D%20%7D%20%3D%20x%5E%7B%5Cfrac%7B2%7D%7B3%7D%20%7D)
There is also an exponent of '6' outside. According to exponential properties, when an exponent is within an exponent, you multiply them together. Therefore:

2x - 1 + 3x + 6 = 90°
5x + 5 = 90
5x = 90 - 5
5x = 85
x = 85/5
x = 17°
Answer:
881280
Step-by-step explanation:
2592x340=881280
3/6 is bigger because it simplifies to 1/2 and 3/8 is below 1/2.
