Question

sendo a=4√2+5√3 e b=5√2-8√3.o valor de a-b é igual a?​

Answer 1

52+25

Explicação passo-a-passo:

\begin{gathered}\sqrt{x} 3\sqrt{2} + 4\sqrt{5}  - (-2\sqrt{2} +\sqrt{5} +\sqrt{5} )\\ \\ \\ (3\sqrt{2} + 4\sqrt{5}) - \sqrt{x} (-2\sqrt{2} + 2\sqrt{5})\\ \\ \\ \sqrt{2}( 3+ 2\sqrt{10})  - 2.(-\sqrt{2} + \sqrt{5} )\\ \\ \\ \sqrt{2} . (5 + \sqrt{10)} \\ \\ \\ = >  5\sqrt{2} + 2\sqrt{5}\end{gathered}x32+45 −(−22+5+5)(32+45)−x(−22+25)2(3+210) −2.(−2+5)2.(5+10)=> 52+25
