Respuesta:
a)[tex]\sqrt{16} +\sqrt{25} -3\sqrt{25} -3\sqrt{27}[/tex]
=4+5 - 3(5) - 3(3)
=4+5-15-9
= -15.
B) [tex]5\sqrt{32} + 4\sqrt{81}+3\sqrt{8}+2\sqrt{64}[/tex]
[tex]20\sqrt{2}[/tex] +4(9) + [tex]6\sqrt{2}[/tex] + 2(8)
[tex]20\sqrt{2}[/tex] + 36 + 6[tex]\sqrt{2}[/tex] + 16
[tex]20\sqrt{2} +6\sqrt{2}[/tex] +52
26[tex]\sqrt{2}[/tex] +52.
36.76955262 +52= 88.76955262
