The answers are:
a) 9 and 5
b) 11 and 7
c) 14 and 8


a² - b² = (a + b)(a - b)

a) The answer is 9 and 5

45= a² - b²
45 = 49 - 4 = 7² - 2² = (7 + 2)(7 - 2) = 9 * 5


b) The answer is 11 and 7

77 = a² - b²
77 = 81 - 4 = 9² - 2² = (9 + 2)(9 - 2) = 11 * 7


c) The answer is 14 and 8

112 = a² - b²
112 = 121 - 9 = 11² - 3² = (11 + 3)(11 - 3) = 14 * 8

Match each simplified form to it's equivalent radical expression. Tiles: 4√3, 3 3√2, 2 3√3, 3√5
lbvjy [14]

Answer:

Step-by-step explanation:

Given the following simplified expressions:

4√3, 3 3√2, 2 3√3, 3√5

It's radical equivalent is :

4√3 = √4² * √3 = √16 * √3 = √16*3 = √48

3 3√2 = 3 * √3² * √2 = √9 * √2 = √9*2 = 3√18

2 3√3 = 2 * √3² * √3 = √9 * √3 = √9*3 = 2√27

3√5 = √3² * √5 = √9 * √5 = √9*5 = √45
