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

The price of a computer was decreased by 30% to £147. What was the price before the decrease?
Sunny_sXe [5.5K]

Answer:

£210

Step-by-step explanation:

A decrease of 30% represents 70% of the original cost.

100% represents the original cost

Divide the price by 70 to find 1% then multiply by 100 for original cost

original cost = \frac{147}{70} × 100 = 2.1 × 100 = £210
