Answer:
2^18
Step-by-step explanation:
2^2
------ * 2^8
2^-8
We know a^b * a^c = a^(b+c)
2^2 * 2^8 = 2^(2+8) = 2^10
2^10
-------
2^-8
a^b / a^c = a^(b- c)
2^(10 - -8) = 2^(10+8) = 2^18

Answer:
She was wrong in her analysis because the sales discount of 25% is the discount on the original cost of the dress and not the purchasing cost of the dress as explained below:
Step-by-step explanation:
From the question:
Purchasing cost price of the dress = £30
However, this cost (£30) was after a 25% Sales Discount
It, therefore, implies that £30 is equal to 75% of the cost price
75% of the original cost price = £30
100% of the original cost price = (30 x100%)/75%
Original cost price = £40
Therefore the 25% discount / savings on the cost
= £ (40-30)
= £10
She saved £10 by buying the dress at £30 instead of the original cost of £40
Distance-Rate-Time Problems. An object that moves at a constant rate is said to be in uniform motion. ... Uniform motion problems may involve objects going the same direction, opposite directions, or round trips. In the diagram below, the two vehicles are traveling the same direction at different rates.
