Question

Bardzo prosze o pomoc nie nawidze matematyki i tg nie umiem rosze pomorzcie.
oblicz:
a) -3 do 2 + (-3)do 2 =?
b) (4-9) do 2 +(4 do 2 -3 do 2) =?
c)(-4) do 4 : 4 do 2 + (-4) do 2 * (-1/2) do 3 =?
d) (1 3/5) do 2 * (-1/2) do 3 + ( -3/4 ) do 2 * 1/3 =?

Answer 1

A) -3 do 2 + (-3)do 2 = 0
b) (4-9) do 2 +(4 do 2 -3 do 2) =(-5)^2+ 10 = 10+10 = 20
c)(-4) do 4 : 4 do 2 + (-4) do 2 * (-1/2) do 3 =16:16+16*(-1/8)=1-2=-1
d) (1 3/5) do 2 * (-1/2) do 3 + ( -3/4 ) do 2 * 1/3 =-8/25+3/16=128/400 +75/400 = 203/400
