Jawab:

sqrt{8} +sqrt{18}=2sqrt{2} +3sqrt{2} =5sqrt{2}

sqrt{27}-sqrt{75} = 3sqrt{3}-5sqrt{3} =-2sqrt{3}

Penjelasan dengan langkah-langkah:

sqrt{8}=sqrt{2 . 2 .2} = sqrt{2^{2}.2 } =2sqrt{2}

sqrt{18}=sqrt{3 . 3 .2} = sqrt{3^{2}.2 } =3sqrt{2}

sqrt{27}=sqrt{3 . 3 .3} = sqrt{3^{2}.3 } =3sqrt{3}

sqrt{75}=sqrt{5 . 5 .3} = sqrt{5^{2}.3 } =5sqrt{3}
