Question

Va rog frumos : efectuatiparanteza - 3 radical din 6 supra 28 inchideti paranteza : paranteza 5 supra radical 24 + 19 supra 7 radical din 6 - 5 supra radical 150 - 2 supra radical 384

Answer 1

(-3√6/27):(5/√24+19/7√6-5/√150-2/√384)=
(-√6/9):(5/2√6+19/7√6-5/5√6-2/8√6)= rationalizam
(-√6/9):(5√6/12+19√6/42-5√6/30-2√6/48)= aducem la acelasi numitor
(-√6/9):[(140x5√6+40x19√6-56x5√6-35x2√6)/1680]=
(-√6/9):[(700√6+760√6-280√6-70√6)/1680]=
(-√6/9):(1110√6/1680)=
(-√6/9)x168/111√6= simplif
-1/3x56/111=-56/333=-0,(168)
