Answer 1

TEMA: OPERADORES MATEMATICOS

 Hallar    (2 * 6) * (3 * 1)

                  21   *   $\frac{23}{2}$

                         $\frac{307}{4}$

$a*b= 3a+\frac{5b}{2}$                                    

$(2*6) = 3(2)+\frac{5(6)}{2}\\\\ (2*6) = 3(2)+\frac{30}{2}\\\\ (2*6) = 6+15\\\\(2*6) = 21$

$a*b= 3a+\frac{5b}{2}$

$(3*1) = 3(3)+\frac{5(1)}{2}\\\\ (3*1) = 9+\frac{5}{2}\\\\ (3*1) = \frac{18+5}{2}\\\\(3*1) = \frac{23}{2}$

 

$a*b= 3a+\frac{5b}{2}$

$(21*\frac{23}{2} ) = 3(21)+\frac{5(\frac{23}{2}) }{2}\\\\ (21*\frac{23}{2} ) = 63+\frac{115}{4}\\\\ (21*\frac{23}{2} ) = \frac{192 +115}{4} \\\\(21*\frac{23}{2} ) = \frac{307}{4}$
