2/7 √14 5/16 * √56

First, simplify the square roots:
√14 = 2√7
√56 = 2√14

Substitute these values back in:
2/7 2√7 5/16 * 2√14

Now, multiply the numbers and square roots separately:
(2 2 5)/(7 16) √(7 * 14)

Calculating the numbers:
20/112 * √98

Simplify the fraction:
5/28 * √98

Finally, simplify the square root:
5/28 √(2 49)

5/28 * 7√2

Therefore, the final answer is 35√2 / 28 or simplified to 5√2 / 4.
