Answer: 31/4

Step-by-step explanation:

The 7 is basically the fraction has been 4/4 7 times, and the 3 means that after that we have 3 left over. So we do:

7×4=28

Then since we have 3 left over:

28+3=31

So the fraction would be 31/4

Answer:

-9

Step-by-step explanation:

$( \sqrt[4]{7} + 2)( \sqrt[4]{7} - 2)( \sqrt{7} + 4) \\ = ( { \sqrt[4]{7} }^{2} - {{2} }^{2} )( \sqrt{7} + 4) [because (a+b)(a-b) = a² - b²]\\ = ( \sqrt{7} - 4)( \sqrt{7} + 4) \\ = { \sqrt{7} }^{2} - {4}^{2}[because (a+b)(a-b) = a² - b²] \\ = 7 - 16 \\ = - 9$
