Bonjour pouvez vous m’aider svpp 26 Donner la valeur exacte des calculs suivants. A=V3*V7 B=V3*48 C=V50 ___ V2 D=V56 ____ V14 E=(3V2) au carré F=V6*V7 _____ V2*

bonjour

A )  √3 x √7 = √21

B ) √3 x √48 = √144 = 12

C )  √50 : √2 =  ( √50 x √2) : ( √2)² = √100 : 2 = 10 ; 2 = 5

D ) √56 ; √14 = ( √56 x √14 ) / ( √14 )² =  √784 /14 = 28 /14 =  2

E = (  3 √2 )² = 9 * 2 = 18

F = ( √6 x √ 7 ) : ( √2 x √3 ) = (√42 x √ 6 ) : ( √6 )² = √252 / 6 = 6√7 / 6 = √ 7

Bonjour,

A = √3 × √7 = √(3×7) = √21

B = √(3×48) = √144 = 12

C = √50/√2 = (√25×2)/√2 = √25 = 5

D = √56/√14 = √(56/14) = √4 = 2

E = (3√2)² = 3² × (√2)² = 9 × 2 = 18

F = (√6×√7)/(√2×√3) = √42/√6 = √(42/6) = √7
