When you have the power multiplied to another power you have to multiply
so
(a^3)^3 - (b^3)^3 = a^9 - b^9

A is correct.

B is incorrect because when you multiply the exponents you get a^18 - b^18

C is incorrect because when you distribute the 2 you get a^6 - b^6

D is correct too

Jana planted 30 tulips. A total of 2/3 of those tulips have bloomed. How many of the tulips that Jana planted have bloomed?

20 tulips. 2/3=20/30 when you multiply both the denominator and numerator by 10.
