2) Simplifique

a) raiz quadrada de 99

B) raiz quadrada de 450

C) raiz quadrada de 800

D) raiz quadrada de 432
façam as contas certinho pf

Answer 1

a) √99 = √11*9 = 3√11
b) √450 = √2*225 = 15√2
c) √800 = √2*400 = 20√2
d) √432 = √3*144 = 12√3

Answer 2

$A) \sqrt{99} = \sqrt{3^{2} } * \sqrt{11} = 3 \sqrt{11} B) \sqrt{ 5^{2} . 3^{2} } . \sqrt{2} = 15 \sqrt{2} C) \sqrt{2^{4} . 5^{2} } = 20\sqrt{2}  D) \sqrt{2^{4} . 3^{2}} * \sqrt{3} = 12 \sqrt{3}$
