svp c'est pour demain

bonsoir

a = V36-3V6+7V144 = V6²-3V6+7V12² = 6 -3V6+94=-3V6+100

b = V81- V2²x3²+4²-3 = V9²-V4x9+16-3 = 9 -V36+13=9-V49=9-V7²= 9-7=2

c = 2/5 +V4+5+7= 2/5 +V16=2/5+V4²=2/5+4 =2/5 +20/5 = 22/5

d = je ne sais pas

a =V4+9+36= V49=V7²=7

b =V9²-V9*3 +V81x3 = 9 -3V3+9V3 =9+6V3

c =V9x7 -5V4x7 +V25*7 =3V7-10V7+5V7 = -10V7+8V7 =-2V7

a = V18/25= V9*2/5² =3/5V2

V4/5 xV27/16 = 2V1/5 x 3/4V3=6/4 V3/5 = 3/2V3/5
