Tính nhanh:

F=\(\left(\frac{6}{8}+1\right)\left(\frac{6}{18}+1\right)\left(\frac{6}{30}+1\right).....\left(\frac{6}{10700}+1\right)\)

Tính :

  \(C=\left(\frac{6}{8}+1\right).\left(\frac{6}{18}+1\right).\left(\frac{6}{30}+1\right).....\left(\frac{6}{10700}+1\right)\)

Giúp mình với mình cần gấp

Tính: A=\(\left(\frac{6}{8}+1\right)\cdot\left(\frac{6}{18}+1\right)\cdot\left(\frac{6}{30}+1\right)\cdot...\cdot\left(\frac{6}{10700}+1\right)\)

Tính giá trị biểu thức sau :

\(B=\left(\frac{6}{8}+1\right)\left(\frac{6}{18}+1\right)\left(\frac{6}{30}+1\right)...\left(\frac{6}{10700}+1\right)\)

\(\left(\frac{6}{8}+1\right)\)\(+\left(\frac{6}{18}+1\right)+\left(\frac{6}{30}+1\right)+...+\left(\frac{6}{10700}+1\right)\)

Tính B = \(\left(\frac{6}{8}+1\right)\)x \(\left(\frac{6}{18}+1\right)\)x \(\left(\frac{6}{30}+1\right)\)x ... x \(\left(\frac{6}{10700}+1\right)\)

Bài 2 : Tính 

\(D=\left(\frac{6}{8}+1\right).\left(\frac{6}{30}+1\right)....\left(\frac{6}{10700}+1\right)\)

                 HÃY CỐ GẮNG GIÚP MÌNH NHA CÁC P

TÍNH:

a.    \(\frac{\left(\frac{1}{9}\right)^6.\left(\frac{3}{8}\right)^7}{\left(\frac{1}{3}\right)^{13}.\left(\frac{1}{2}\right)^{22}.3^6}\)

b.   \(\frac{5^{-6}.\left(\frac{1}{2}\right)^{13}}{\left(\frac{1}{5}\right)^7.\left(\frac{1}{8}\right)^4}\)

    Giúp mik vs các bạn nha!!!

\(=3+\left(\frac{2}{a}+\frac{2}{b}+\frac{2}{c}\right)+\left(\frac{6}{3a+1}+\frac{6}{3b+1}+\frac{6}{3c+1}\right)\)

\(\ge3+\frac{18}{a+b+c}+\frac{54}{3\left(a+b+c\right)+3}\ge3+18+9=30\)
