Question

Calculați: √25/16; √6/4; √75/36; √165/49; √245/100​

Answer 1

Răspuns:

Explicație pas cu pas:

√25/16=5/4

√6/4=√6/√4=√6/2

√75/36=5√3/6

√165/49=√165/√49=√165/7

√245/100=7√5/10

Answer 2

Răspuns:

$\sqrt{\frac{25}{16} } =5/4\\\\\sqrt{\frac{6}{4} } =\frac{\sqrt{6} }{\sqrt{4} } =\frac{\sqrt{6} }{2} \\\\\sqrt{\frac{75}{36} } =\frac{5\sqrt{3} }{6} \\\\\sqrt{\frac{165}{49} } =\frac{\sqrt{165} }{7} \\\\\sqrt{\frac{245}{100} } =\frac{\sqrt{245} }{\sqrt{100} } =\frac{7\sqrt{5} }{10}$
