Question

корень 77/2 × корень 11× корень 7/2

Answer 1

$\sqrt{\frac{77}{2}}* \sqrt{11}* \sqrt{\frac{7}{2}}= \sqrt{\frac{77*11*7}{2*2}}= \sqrt{\frac{7^{2}*11^{2}}{2^{2}} } = \frac{7*11}{2}= 38,5$

Answer 2

$\sqrt{ \frac{77}{2} \times 11 \times \frac{7}{2} } = \sqrt{ \frac{5929}{4} } = \frac{77}{2} = 38.5$
