#"C < B < D < A"#

#"A" = 1.5 × 10^3#
#color(white)(A) = 1.5 × 1000#
#color(white)(A) = 1500#

#"B" = 1.4 × 10.1#
#color(white)(B) = 14.14#

#"C" = -2 × 10^3#
#color(white)(C) = -2 × 1000#
#color(white)(C) = -2000#

#"D" = 1.4 × 10^2#
#color(white)(D) = 1.4 × 100#
#color(white)(D) = 140#

Only #"C"# is negative. So it’s smallest of all.

Order of #"A", "B", "C"# and #"D"# is

#"C < B < D < A"#
