Question

Considerando A= (0,3)³, B= (1+1/3)elevado a -2 e C= (+1,35)elevado a -1, calcule:

a) A+B+C

b) B(elevado a 0)

c) A(elevado a -2)

Answer 1

A = ( 0,3)³ = 0.027 ****  OU   ( 3/10)³  = 27/1000****
B = ( 1/1 + 1/3)⁻²  =  ( 3 + 1)/3 = ( 4/3 )⁻²  =  ( 3/4)² = 9/16 ***
C = ( 1,35)⁻¹  =( 135/100)⁻¹  =  ( 100/135) =( 20/27 )

1
A + B + C =  27/1000 + 9/16 + 20/27 =
MMC = 432000
( 11664 + 243000 + 320.000)/432000 = 574664/432.000= 71833/54000 = 

2
B⁰ =  ( 9/16)⁰  = 1 ****
3
( 27/1000 )⁻²  = ( 1000/27)²  =
