oblicz w pamięci:
a) (-3)do potęgi 2
-10 do potęgi 2
b) (-5)do potęgi2 - (-2)
4*(-7)+1
c) 125 : (-5)+(-2)
(-3)+(-6)*(-5)

a) (-3)do potęgi 2 = 9
-10 do potęgi 2 = 100
b) (-5)do potęgi2 - (-2) = 25 + 2 = 27
4*(-7)+1 = -28 + 1 = - 27
c) 125 : (-5)+(-2) = -25 - 2 = -27
(-3)+(-6)*(-5) = -3 + 30 = 27
a) (-3)do potęgi 2 = (-3)*(-3) = 9
-10 do potęgi 2 = (-10)*(-10) = 100
b) (-5)do potęgi2 - (-2) = (-5)*(-5) + 2 = 25 + 2 = 27
4*(-7)+1 = -28 + 1 = -27
c) 125 : (-5)+(-2) = (-25) - 2 = -27
(-3)+(-6)*(-5) = (-3) + 30 = 27
Mam nadzieję, że pomogłem i liczę na naj.:)
