​

Answer 1

Answer:  $\dfrac{1316}{3}$

Step-by-step explanation:

To find:  $1 \div 1 \times 2\times 3+1 \div2 \times3 \times4 + 1 \div3\times 4 \times 5+ 14\times 5 \times 6$

$1 \div 1 \times 2\times 3+1 \div2 \times3 \times4 + 1 \div3\times 4 \times 5+ 14\times 5 \times 6\\\\= \dfrac{1}{1} \times 6+\dfrac{1}{2} \times 12+ \dfrac{1}{3} \times 20 + 420\\\\=6+6+\dfrac{20}{3} +420\\\\=432+\dfrac{20}{3}\\\\=\dfrac{1296+20}{3} \\\\=\dfrac{1316}{3}$

Hence  the answer is $\dfrac{1316}{3}$

Answer 2

Answer:  \dfrac{1316}{3}

Step-by-step explanation:

To find:  1 \div 1 \times 2\times 3+1 \div2 \times3 \times4 + 1 \div3\times 4 \times 5+ 14\times 5 \times 6

1 \div 1 \times 2\times 3+1 \div2 \times3 \times4 + 1 \div3\times 4 \times 5+ 14\times 5 \times 6\\\\= \dfrac{1}{1} \times 6+\dfrac{1}{2} \times 12+ \dfrac{1}{3} \times 20 + 420\\\\=6+6+\dfrac{20}{3} +420\\\\=432+\dfrac{20}{3}\\\\=\dfrac{1296+20}{3} \\\\=\dfrac{1316}{3}

Hence  the answer is \dfrac{1316}{3}
