Answer 1

Aplici doua formule:

Ma = (a+b)/2

Mg = V(a*b)

a) Ma = (32V6 + 2V6)/2

Ma = 34V6/2

Ma = 17V6

Mg = V(32V6 * 2V6)

Mg = V(64 * 6)

Mg = 8V6

Ma + Mg = 17V6 + 8V6 = 25V6

b) Ma = (3V2 + 27V2)/2

Ma = 30V2/2

Ma = 15V2

Mg = V(3V2 * 27V2)

Mg = V(81 * 2)

Mg = 9V2

Ma + Mg = 15V2 + 9V2 = 24V2

c) Ma = (36V7 + 4V7)/2

Ma = 40V7/2

Ma = 20V7

Mg = V(36V7 * 4V7)

Mg = V(144 * 7)

Mg = 12V7

Ma + Mg = 20V7 + 12V7 = 32V7

d) Ma = (3 + 75)/2

Ma = 78/2

Ma = 39

Mg = V(3 * 75)

Mg = 5V3 * V3

Mg = 5 * 3

Mg = 15

Ma + Mg = 39 + 15 = 54
