Answer 1

1) V8= 2V2

V18 = 3V2

V4 =2

V50 =5V2

(2+2V2-6V2)(2+5V2-V2) = 2(1+V2-3V2)(2+5V2-V2) = 2(2+5V2-V2+2V2+10-2-6V2-30+6) =2(-14-2V2) = -28-4V2

2) dam factor comun pe (2V5+1)

(2V5+1)(2V5+1-2V5+1) = (2V5+1)*2 = 4V5+2

3) amplificam pe  V10 cu V2

3-2V5-V2(7+4V5)/V2+13 =

16-2V5-7-4V5 = 9-6V5 = 3(3-2V5)

4) Media geometrica are formula mg=  V(a*b)

mg = V(x*y) = V[(140+84V2)/(5+3V2)] = V[28(5+3V2)/(5+3V2)] = V28 = 2V7
