Answer 1

a)

         4      2        2
A = 3   .  5     .  7

√A = √81.√25.√49
√A = 9.5.7
√A = 9.35

R.: √A = 315
_______________
b)

          4         2
B = 2      .  3

√B = √16.√9
√B = 4.3

R.: √B = 12
_______________
c)

C = 2³.7
D = 2.3².7³

√C
= √8.√7 = 2√2.√7 = 2√14

√C = 2√14

√D
= √2.√9.√7³
= √2.3.√343
= 3√2.√49.√7
= 3√2.7√7
= 3.7.√2.√7
= 21√√14

√C.√D
= 2√14.21√14
= 2.21.√14.√14
= 42.14
= 588
