Exercitiul 27 va rog mult punctul b

Answer 1

x/(4√2+√3)=(3√2-√3)/(4√2+2√3)
x(4√2-√3)/(4√2+√3)(4√2-√3)=(3√2-√3)(4√2-2√3)/(4√2+2√3)(4√2-2√3)
x(4√2-√3)/(32-3)=(24-4√6-6√6+6)/(32-12)
x(4√2-√3)/29=(30-10√6)/20
x(4√2-√3)/29=(3-√6)/2
x=29(3-√6)/2(4√2-√3)
x=29(3-√6)(4√2+√3)/2(4√2-√3)(4√2+√3)
x=29(3-√6)(4√2+√3)/2(32-3)
x=29(3-√6)(4√2+√3)/2×29
x=(3-√6)(4√2+√3)/2
x=(12√2-4√12+3√3-√18)/2
x=(12√2-8√3+3√3-3√2)/2
x=(9√2-5√3)/2
