Trên cùng nửa mặt phẳng bờ chứa tia Ox , vẽ hai tia Oy và Oz sao cho góc xOy =40 độ , góc xOz =80 độ

a)Tính số đo góc yOz

b)Tia Oy có phải là tia phân giác của góc xOz ko vì sao

c)Vẽ tia Om là tia đối của tia Oy . Tính số đo góc xOm

X + 6 chia hết cho X - 4

(x-\(\frac{1}{3}\)).(\(\frac{1}{2}-\frac{2}{5}-\frac{5}{6}\))-\(\frac{1}{2}\)=\(\frac{3}{10}-\frac{1}{4}\)

tìm số nguyên n để A= \(\dfrac{3n+2}{n}\)có giá trị là số nguyên tố

So sánh : \(2^{100}\) với \(10^{31}\)
