You have alot of question so I will say if it is right or wrong and explain if it is wrong
1. correct 10a√a
2.correct 2ab ∛b^2
3. incorrect, answers are 2nd one and fourth one
x^3√(2xy)-4x√(2xy)
(2x^3y-4x)√(2xy)
4. incorrect, answer is 6√3
5.incorrect, answer is last one 3√6-3√2
6. correct
7. incorrect, if a>b then a/b is not a fraction, that means that is a rational number that is greater than 1 and exponents to numbers greater than 1 get bigger
answer is 3rd and 4th
![\sqrt[b]{100^{a} }](https://tex.z-dn.net/?f=%20%5Csqrt%5Bb%5D%7B100%5E%7Ba%7D%20%7D%20)
expression is greater han 100
8. incorrect, since it is the 3rd root, reverse it and get 3^3=27
answer is 27x^(3/5)
9. incorrect, the answer is 4x^(2/3) because pemdas says that the exponents before multiplication
10. incorrect, answer is use pemdas
