Va rog, urgent!Dau coronita!

Answer 1

x=2(2+√2)(2-√2)(√4-1)=(4-2)(4-2)=2*2=4

y=[(1-√18)/√3-(2-√98)/√2+√2-1/√3]*(-√3/√8)⁻¹=[(1-3√2)/√3-(2-7√2)/√2+√2-1/√3](2√2/-√3)=[(√2-6-2√3+7√6+√6-√2)/√6](-2√2/√3)=[(8√6-2√3-6)/√6](-2√2/√3)=(-32√3+4√6+4√3)/√2=-32√6+8√2+4√6)/2=-16√2+4√2+2√6=-14√6+4√2

ma=(x+y)/2=(4-14√6+4√2)/2=2-7√6+2√2

mg=√xy=√[(-14√6+4√2)4]=2√2(-7√6+2√2)
