Answer 1

Răspuns:

Explicație pas cu pas:

a) a = √6 ; b = √600 = 10√6

ma(a,b) = (a+b)/2 = (√6+10√6)/2 = 11√6/2

mg(a,b) = √(a·b) = √(√6·10√6) = √(6·10) = 2√15

b) a = √[(4-2√5)²] = I4-2√5I = I√16-√20I = 2√5-4

b = √[(4+2√5)²] = I4+2√5I = 4+2√5

ma(a,b) = (a+b)/2 = (2√5-4+4+2√5)/2 = 4√5/2 = 2√5

mg(a,b) = √(a·b) = √[(2√5-4)·(2√5+4)] = √(20-16) = √4 = 2
