1. 2(2)(1) =4
2. (-1)-4(0) = -1
3. (-5)[tex]^2[/tex] + (7) = 25+7 = 32
4. [tex] sqrt{3(3)+2(-4)} [/tex] = [tex] sqrt{9-8} [/tex] = [tex] sqrt{1} [/tex] = 1
5. the question is unclear.
6. 3(8+(-2)-2((8)-8(-2) = 3(6)-2(8+16) = 18 -2(24) = 18 – 48 = -30
7. (3(4)(0-8) = (12)(-8) = -96
    (0-2) = -2
8. (5)[tex]^2[/tex]+4(5)-5 = 25+20-5 = 45-5 =40
    (3)[tex]^2[/tex]-3-2 = 9-3-2 = 6-2 = 4
9. [tex] sqrt{2(4)-5+7(2)} [/tex] = [tex] sqrt{8-5+14} [/tex] = [tex] sqrt{8-19} [/tex] = [tex] sqrt{-11} [/tex]
10. ((5+3)/4-15/2(5)(-1) = (8)/4-15/-10 = 2-15/-10 = 2 + [tex] frac{3}{2} [/tex] = [tex] frac{7}{2} [/tex]

Thus the questions about Evaluating The Following Algebraic Expression 1.) 2xy when x=2 and y=1 2.) x-4y when x=-1 and y=0 3…., hopefully with this can help solve your problem.
