Question

steps on how to solve these problems? please and thank you

Answer 1

\[\sqrt{11}+\sqrt{13}+\sqrt{13}\]

Answer 2

\[5\sqrt{175}-\sqrt{54}+2\sqrt{63}\]

Answer 3

You want them simplified in radical form?

Answer 5

If yes, then the first is just like having same terms twice, x + x, which is 2x\[\sqrt{11} + \sqrt{13} + \sqrt{13} = \sqrt{11} + 2 \sqrt{13}\]

Answer 6

the second: (find a common multiple for the radicals)\[5 \sqrt{175} - \sqrt{54} + 2\sqrt{63} \rightarrow 5 \sqrt{7 \times 25} - \sqrt{6 \times 9} + 2 \sqrt{7 \times 9 }\]Factoring...\[25 \sqrt7 + 6 \sqrt7 -3 \sqrt6 = 31 \sqrt7 -3 \sqrt6\]

Answer 7

Let me know if anything does make sense there.
