10 is correct. 14 is correct, but if I were a teacher, I'd deduct marks because 3^3 x 11 means 3 to the power of 3 times 11, which is not 297. You would want to write 3 x 3 x 11 as the prime factorisation.
#16 is incorrect. 4% = 0.04 and 2/5 ≠ 0.04.
#11 and #12 will need to be retyped more clearly in order for me to confirm them.
