Simplify square root<br>​
Tasya [4]

Answer:

Here is the rule: when a and b are not negative

√(ab) = √a × √b

Example: simplify √8

√8 = √(4×2) = √4 × √2 = 2√2

(Because the square root of 4 is 2)

In other words 2 x 4 = 8 = √2 x 4 but 4 can be simplified more (2 x 2) so 2 (previous 4) moves to the left of the square root leaving  2√2

To simplify a square root: make the number inside the square root as small as possible (but still a whole number)

or you can use a simplifying square root calculator.

Multiply the original price by 70%:


52 x 0.70 = 36.40


The sale price is $36.40
