Question

a = | √5 - 3 |
b = 3 + √5
Ma, Mg=?

Answer 1

a= |√5-3|

a=3-√5

b=3+√5

mₐ=a+b/2

mₐ=3-√5+3+√5/2

mₐ=6/2

mₐ=3

mg=√a×b

mg=√(3-√5)(3+√5)

mg=√3²-(√5)²

mg=√9-5

mg=√4

mg=2

Answer 2

a=3 - rad(5)

b=3 + rad(5)

ma = (a+b)/2 = (3 - rad(5) + 3 + rad(5)) / 2 = 3

mg = rad((3-rad(5)) (3+rad(5))) = rad(9 - 5)=2

ma=3

mg=2
