Odpowiedź:
√120 = √4*√30 = 2√30
[tex]\sqrt{148}[/tex] = √4*√37 = 2√37
[tex]\sqrt{88}[/tex] = √4*√22 = 2√22
[tex]\sqrt{92}[/tex] = √4*[tex]\sqrt{23}[/tex] = 2[tex]\sqrt{23}[/tex]
[tex]\sqrt{1000}[/tex] = [tex]\sqrt{100} *\sqrt{10}[/tex] = 10 [tex]\sqrt{10}[/tex]
[tex]\sqrt{316}[/tex] = √4*[tex]\sqrt{79}[/tex] = 2 [tex]\sqrt{79}[/tex]
