help me!
B1: Tính A=(1/7+1/23-1/1009) : (1/7+1/23-1/1009+1/7.1/23.1/9) +1:(30.1009-160)
B=(151515/161616+17^9/17^10)-(1500/1600+1616/1717)
Các bạn giúp mình với
B= (151515/161616+17^9/17^10)-(1500/1600-176/187)
Tinh: B=\(\left(\frac{151515}{161616}+\frac{17^9}{17^{10}}\right)-\left(\frac{1500}{1600}-\frac{176}{187}\right)\)

Tính giá trị biểu thức:
(\(\frac{15.15.15}{16.16.16}\)+\(\frac{17^9}{17^{10}}\)) . (\(\frac{1500}{1600}\)- \(\frac{176}{187}\))
tính giá trị biểu thức sau:\(\frac{3}{7}-\frac{3}{17}+\frac{3}{171}-\frac{3}{1717}\)\(\div\frac{9}{7}-\frac{9}{17}+\frac{9}{171}-\frac{9}{1717}\)
