Question

rozwiąż przykłady : a ) 7*(-4) - 2 * (-3)*(-5) + 2*(-5)^2 - (-5)^-2

b ) 3 - (-3)^2 - (-3) ^3 - (-3) ^4

c ) (-4)^3 - 4 ^3 - [ (-5)^4 - 5^4 ]

d ) 3 * [7 - (-2)^3 ] - [ 1 - ( 2-2^2 ) ]

e) 3 - {9 - [ 18 - (-2)^3 * (-3)^2 ] }

z góry bardzo dziękuje ;) .

Answer 1

a) ...= -28 - 30 +50 - 25 = 50 - 83 = -33

b) ...= 3 - 9 + 27 - 81 = 30 - 90 = - 60

c) ...= 64 -64 - (625-625) = 0 - 0 = 0

d) ...= 3* [7 - (-8)] - [1-(2-4)] = 3*15 - 1+2 = 45 - 3 = 42

e) ...= 3 - {9 - [ 18-(-8)*9]} = 3- [9-(26*9)] = 3-(9-234) = 3-(-225) = 228
