What he said^

Answer 4

haha thanks

Answer 5

Hint: Since 28 = 4 x 7 and 63 = 9 x 7, then we can write the above as : \[\sqrt{ 4 \times 7} + \sqrt{9 \times 7}\]

Also since \[\sqrt{a \times b} = \sqrt{a} \times \sqrt{b}\] we can re-write the above as \[\sqrt{4} \times \sqrt{7} + \sqrt{9} \times \sqrt{7}\]
