Question

CALCULATI.............​

Answer 1

Răspuns:

A=$\sqrt{5,76} *0,5 -1,1^{2}$

A=$\sqrt{576/100} *0,5 -(\frac{11}{10})^2$

A= √576/√100 *5/10 -121/100

A =24/10 *5/10 -121/100

A=$\frac{120}{100} -\frac{121}{100} = -\frac{1}{100}$

B=$\frac{4}{5} * \sqrt{2,56} -\sqrt{1,96}$

B=4/5 *√256/100 - √196/100

B=4/5*√256/√100 -√196/√100

B=4/5*16/10 -13/10

B=$\frac{64}{50} -\frac{13}{10}$

B=$\frac{64}{50} -\frac{65}{50} = -\frac{1}{50}$

A/B =$-\frac{121}{100} :-\frac{1}{50} =\frac{121}{100}*50 =\frac{121}{2}$
