Question

se a= 0,666 b= 1,333 e c= ,01414 calcule entao a.b-¹ + c? 

Answer 1

a (0,666) . b(1,333) ^-1 + c (0,1414) =
0,666 . 1/1,333 + 0,1414 =
0,4996 + 0,1414 = 0,641

Answer 2

b = 1,3333...
b = 4/3
b = 4/3 -¹ = 3/4
b = 3/4 = 0,75

a = 0,6666 = 2/3

2/3 * 3/4 = 6/12 = 0,5

Portanto:

0,5 + 0,1414 = 0,64141...
