Resolva as expressoes

Answer 1

a) $\sqrt{64} +2^3 + 35 = 51$

     $8+8+35\\16+35=51$

b) $\sqrt{144} + 36 - \sqrt{81} = 39$

  $12+36-9\\48-9=39$

c) $2^3+3^2+2-5^0= 18$

  $8+9+2-1\\17+2-1\\19-1=18$

d) $\sqrt{25} - \sqrt{16} + \sqrt{46} = 7,78$

   $5-4+6,78\\1+6,78=7,78$

e) $38+6^3-8+\sqrt{36} = 252$

   $38+216-8+6\\254-8+6\\246+6=252$

f) $2$ × $3^2+\sqrt{121} = 29$

   $2$ × $9+11=29$

g) $\sqrt{25} + \sqrt{49} - \sqrt{64} = 4$

   $5+7-8\\12-8=4$

h) $2^3+3^2-3^2+5^2= 33$

   $8+9-9+25\\17-9+25\\8+25=33$
