. Tính nhanh: a) (45×105-225)-(210+42×95) b) (47×105-235)-(168+42×96) Giúp với ạ. E đang cần gấp.
a) \(\left(45x105-225\right)-\left(210+42x95\right)\)
\(=45x\left(100+5\right)-225-210+42x\left(100-5\right)\)
\(=4500+45x5-225-210+4200-42x5\)
\(=4500+4200+45x5-42x5-225-210\)
\(=8700+5x\left(45-42\right)-435\)
\(=8700+15-435=8280\)
