Explicație pas cu pas:

a={(-25)(-3) - [(-72):(-3) - (-96):(+6)]}:(-21+16) =

={75 - [24 - (-16)]}:(-5) =

=[75 - (24 +16)]:(-5) =

=(75 - 40):(-5) =

=(35):(-5) =

=-7

b=(-54+2³*7)² - 6³:(2³*3²) + (-4³ + 3²*7)² - [(-3)³]²:$(-3)^{5}$ =

=(-54+8*7)² - 216:(8*9) + (-64 + 9*7)² - $(-3)^{6}:(-3)^{5}$ =

=(-54+56)² - 216:72 + (-64 + 63)² - (-3)=

=2² - 3 + (-1)² + 3 =

=4 - 3 + 1 + 3 =

=5

a+b = -7+5 = -2

$c=(-9*7+4^{3})^{6} + (-2^2)^{3}:(-2)^{5} + 6^{2}:(-5*3^{2} + 3^{2}*2^{2}) =$$=(-63+64})^{6} + (-64):(-32) + 36:(-5*9 + 9*4) =$

$=1^{6} + 2 +36:(-45 + 36) =$

$=1 +2 + 36:(-9) =$

$=1 +2 -4 =\\=-1$

$d=-6^2:[(-2^2)*3]+(-2^3*3+5^2)^{13}-8^2:(-2^2)^3 - (-50+2^4*3)^2=$

$=-36:[(-4)*3]+(-8*3+25)^{13}-64:(-4)^3 - (-50+16*3)^2=$

$=-36:(-12)+(-24+25)^{13}-64:(-64) - (-50+48)^2=$

$=3+1^{13} -(-1) - (-2)^2=$

$=3+1 +1 -4=\\=1$

$d-c=1-(-1)=1+1=2$
