b) Ѵ64 - Ѵ49

c) 15 + Ѵ81

d) 2 + Ѵ4/9

e) – 3 + Ѵ16

f) – 5 - Ѵ36

g) 3 Ѵ56 – 9

g) Ѵ1/4 + Ѵ9/2

Me ajudem por favor​

Answer 1

a) Ѵ1 + Ѵ0= Vx1+Vx0= V

b) Ѵ64 - Ѵ49= Vx64-Vx49= 64v-49v= 15v

c) 15 + Ѵ81= 15xVx81= 3 (5+Vx27)= 3(5+27v)

d) 2 + Ѵ4/9= 2+Vx4/9 = 2+4v/9

e) – 3 + Ѵ16= -3+Vx16= -3+16v

f) – 5 - Ѵ36= -5-v-36= -41-v

g) 3 Ѵ56 – 9= 3Vx56-9= 168v -9= 3(56v-3)

h)Ѵ1/4 + Ѵ9/2= Vx1/4 + Vx9/2 = V/4+V9/2= 19/4 V
