Calculați:
A=3√128+6√108-8√18-10√27=
B=5√700-2√200+3√567+4√50=

Answer 1

A= 3√128+6√108-8√18-10√27
=Descompunem radicalii: =3•6√2+6•6√3-8•3√2-10•3√3=18√2+36√3-24√2-30√3=6√2+6√3
B=5√700-2√200+3√567+4√50=La fel descompunem radicalii, 5•10√7-2•10√2+3•3√63+4•5√2=50√7-20√2+3•3•3√7+20√2=50√7-20√2+27√7+20√7=97√7-20√2
