Question

(1+1/14)(1+1/14)×(1+1/15)×(1+1/16)×(1+1/17) mong các xem và giải giúp mình với

Answer 1

\(=\dfrac{15}{14}\times\dfrac{15}{14}\times\dfrac{16}{15}\times\dfrac{17}{16}\times\dfrac{18}{17}=\dfrac{15}{14}\times\dfrac{18}{14}=\dfrac{135}{98}\)

Answer 2

\(\left(1+\dfrac{1}{14}\right)\left(1+\dfrac{1}{14}\right)\times\left(1+\dfrac{1}{15}\right)\times\left(1+\dfrac{1}{16}\right)\times\left(1+\dfrac{1}{17}\right)\)

\(=\dfrac{15}{14}.\dfrac{15}{14}.\dfrac{16}{15}.\dfrac{17}{16}.\dfrac{18}{17}\)

\(=\dfrac{15}{14}.\dfrac{18}{14}\)

\(\dfrac{135}{98}\)

Answer 3

= 135/98
