Question

wyznacz A U B ,A∩B ,A/B ,A/B wiedzac ze a) A={-4, -2, 0 , 2 , 4 } , B= {-2, -1 , 0, 1 , 2} b) A= prosze o szybka pomocccccc

Answer 1

A U B  = {-4, -2,-1, 0 ,1, 2 , 4 }

A∩B = {-2,0,2}

A/B = {-4,4}

B/A ={ -1,1}

Answer 2

a) A U B ={-4,-2-1,01,2,4}

    A ∩ B = {-2,0,2}

    A / B ={-1,1}

    A / B ={-4,4}
