Răspuns:
a=16 /5×(12/9+11/3)×√2=16√2
12/9 + 11/3 = 12/9 + 33/9 = 45/9 = 5
16/5 *5 = 16
16 * √2 = 16√2
[tex] \frac{16}{5} \times ( \frac{12}{9} + \frac{11}{3}amplifcam \: cu \: 3 ) \times \sqrt{2} = \frac{16}{5} \times \frac{12 + 33}{9} \times \sqrt{2} = \frac{16}{5} \times \frac{45}{9} \times \sqrt{2} = \frac{16}{1} \times 1 \times \sqrt{2} = 16 \sqrt{2} [/tex]
