Answer 3

aritee i thought so but can you simplify it?

because they both go into 7

Answer 5

\[7= \sqrt{7} + \sqrt{7}\]
\[2 \times \sqrt{7}\times \sqrt{7} \sqrt{3 \times 7} \div \sqrt{7} \times \sqrt{7}\]

Answer 6

************ sorry I mean \[7= \sqrt{7} x \sqrt{7}\]

Answer 7

which means : \[2\sqrt{3x7}\]
\[2 \sqrt{21}\]
