-4^2-(3/2)^2x2/9+6除|-2/3^3|9又14/25x(-15)-(2.5+1/8-3又1/2+1又7/8)-4^2-(3/2)^2x2/9+6除|-2/3^3|9又14/25x(-1

-4^2-(3/2)^2x2/9+6除|-2/3^3|9又14/25x(-15)-(2.5+1/8-3又1/2+1又7/8)
-4^2-(3/2)^2x2/9+6除|-2/3^3|
9又14/25x(-15)-(2.5+1/8-3又1/2+1又7/8)

-4^2-(3/2)^2x2/9+6除|-2/3^3|9又14/25x(-15)-(2.5+1/8-3又1/2+1又7/8)
-4^2-(3/2)^2x2/9+6÷|-2/3^3|
=-16-9/4x2/9+6÷8/27
=-16-0.5+20.25
=3.75
9又14/25x(-15)-(2.5+1/8-3又1/2+1又7/8)
=(10-1/25)x(-15)-(2.5-3又1/2)-(1/8+1又7/8)
=-10×15+1/25×15+1-2
=-150+0.6+1-2
=-150.4
