  • √18-√32+√2 (√45+√18)-(√8-√25) (√48-4√1/8)-(3√1/3-4√0.5)

    =√18-√32+ √90+√36-(√8-√25) (√48-4√1/8)-(3√1/3-4√0.5)

    =3√2-4√2+ 3√10+6-(2√2-5)(4√3-√(16/8))-(√(9/3)-√(16*0.5))

    =6-√2+ 3√10-(2√2-5)(4√3-√2)-(√3-√8)

    =6-√2+ 3√10-(8√6-20√3+5√2-4)-√3-2√2)

    =6-√2+ 3√10-8√6+20√3-5√2+4-√3-2√2

    =10+2√2+ 3√10-8√6+19√3

    √18-√32+√2

    =3√2-4√2+√2

    =0

    (√45+√18)-(√8-√25)

    =3√5+3√2)-(2√2-5)

    =3√5+√2+5

    (√48-4√1/8)-(3√1/3-4√0.5)

    =4√3-√(16/8))-(√(9/3)-√(16*0.5))

    =4√3-√2-(√3-√8)

    =4√3-√2-√3+2√2

    =3√3+√2
