Question

2 + 3 − 2 − 3 =
2- 102 − 52 + 4 − 2 =
3- ab + bx +ay +xy =
4- 3am + 2bm – 6an -4bn =
5- ax – bx + ay – by =

Answer 1

Respuesta:

2 + 3 − 2 − 3 =

$=5-2-3\\=3-3\\=0$

2- 102 − 52 + 4 − 2 =

$=-100-52+4-2\\=-152+4-2\\=-148-2\\=-150$

3- ab + bx +ay +xy =

$=-ab+ay+bx+xy+3$

4- 3am + 2bm – 6an -4bn =

$=-3am-6an+2mb-4bn+4$

5- ax – bx + ay – by =

$=-ax+ay-xb-by+5$
