Question

(3) simplify:
$(3 - 5 \times 10 - 5 \times 125) \div 5 - 2 \times 6 - 5$
​

Answer 1

Answer:

$(3-5$ × $10-5$ × $125)$ ÷ $5-2$ × $6-5$

$=(3-50-5$ × $125)$ ÷ $5-2$ × $6-5$

$= (3-50-625)$ ÷ $5-2$ × $6-5$

$= (30-50-625)$ ÷ $5-12-5$

$= (-47-625)$ ÷ $5-12-5$

$= -672$ ÷ $5-12-5$

$= 134.4-12-5\\=-146.4-5\\=-151.4$
