Question

решите примери под номером 1519

Answer 1

a)(4.5^2-19.25)^3-1.7 и (1.1^2-1.3^2)/0.2
(4.5^2-19.25)^3-1.7=(20.25-19.25)^3=1-1.7=-0.7
(1.1^2-1.3^2)/0.2=(1.1-1.3)(1.1+1.3)/0.2=-0.2*2.4/0.2=-2.4
-0.7>-2.4
(4.5^2-19.25)^3-1.7 > (1.1^2-1.3^2)/0.2
б) (-0.1)^2*(6.5^2-43.245) и (2.5-3)^3*(-2)^3-1.99
(-0.1)^2*(6.5^2-43.245)=0.01*(-0.995)=-0.00995
(2.5-3)^3*(-2)^3-1.99=-0.0625*(-8)-1.99=-2.49
-0.00995>-2.49
(-0.1)^2*(6.5^2-43.245)> (2.5-3)^3*(-2)^3-1.99

Answer 2

1). -0.7 больше -2.4
2) -0.00995 меньше 5.885
