Question

completati tabelu a=13/32 b=9/32 a+b=? a-b=?

​

Answer 1

Răspuns:

Explicație pas cu pas:

a = 13/32 şi  b = 9/32

_________________

a + b = 13/32 + 9/32 = ( 13+9)/32 = 22/32

(22/32)⁽² = (22:2)/(32:2) = 11/16

________________________________

a - b =  13/32 - 9/32 = ( 13-9)/32 = 4/32

(4/32)⁽⁴ = (4:4)/(32:4) = 1/8 = 0,125

Answer 2

Răspuns:

Explicație pas cu pas:

a=13/32 b=9/32

a+b=13/32+9/32=(13+9)/32=22/32=11/16

a-b=13/32-9/32=(13-9)/32=4/32=1/8
