Ashton estimates the square root of 50 in the following way: √50=2 √25=2×5=10.(a) Expkain why his reasoning is incorrect. (b) Estimate the square root of 50 to the nearest tenth without using your calculator. Show your work.

His reasoning is not correct because √50 = √2 × √25 and not 2√25

b) 7.1 to the nearest tenth

Step-by-step explanation:

Using the laws of surds, we know that

√a × √b = √ab

and

a√b = √a² × √b

As such,

√50 = √2 × √25 (since 2 × 25 = 50)

= √2 × 5

= 5√2

= 5 × 1.414 where √2 = 1.414

= 7.07

≈ 7.1 to the nearest tenth

both equations and proportions are better.

well if he bought them at 5 cedis each sold them at 7 cedis each then he would make a profit of 2 cedis of each book. if in total he made 150 cedis profit that means he sold 75 books. he lost 12 books at the start so that means he originally bought a total of 82 books.
