Question

Calcule as expressões:
a) 2⁵-3².2
b)13⁰-3.2³
c) 10⁴+2.10³-6.10²-17.10+10⁰
d)2.3⁵-5.3+6.3²+3-7.3⁰

Answer 1

a) 2⁵-3².2 = 
    32 -9.2=
    32 - 18= 14

b)13⁰-3.2³ = 
     1 - 3,8 =
      1 - 24 = -23

c) 10⁴+2.10³-6.10²-17.10+10⁰ =
     10000 + 2000 - 600 - 170 + 1 = 11. 231
     

d)2.3⁵ - 5.3 + 6.3² + 3 - 7.3⁰ =
   2.243 - 15 + 6.9 + 3 - 7.1 = 521
