Question

What is the exact value of the expression 5sqrt13+sqrt 6 - 7sqrt 13

Answer 1

\( \sqrt{13} \) and \(\sqrt{6} \) are simple radicals that can't be simplified any further.
Treat them as variables.

You can combine like variables.
\( 5\sqrt{13}\) and \(-7\sqrt{13} \) are like terms.
\(\sqrt{6} \) is not a like term to \(\sqrt{13} \).

Answer 2

Now wat

Answer 3

If you had \( 5x + y - 7x\),
you'd be able to combine the terms with x together, but since there is only one term with y, it would remain the same, so
\( 5x + y - 7x = -2x + y\)

Treat \( \sqrt{13} \) as x, and treat \(\sqrt{6} \) as y.
