Boa noite Veronia

a) 3√12 * √24 = 3√12*√12*√2 = 36√2

b) 3√12 + √24 = 3√12 + √12*√2 = √12*(3 + √2)

c) 3√12² = 3*12 = 36 

d) 3√12/√24 = 3/√2 = 3√2/2 

.

Answer 2

A) 3√12×√24
= 3√288

B) 3√12 + √24
= 3√12 + √(12×2)
= 3√12 + √12×√2
= (3+√2)√12


C) 3√12²
= 3√144
= 3×12
= 36

D)3√12 / √24
= (3√12) / √24 × √24 / √24
= (3√12×√24)/(√24×√24)
= 3√288 / √576
= 3√288 / 24
= √288 / 8
