3 $\sqrt{3}$ and $\sqrt{7}$

Step-by-step explanation:

Simplifying surds is similar to collecting like terms in algebra.

If the surds have the same value then collect them by adding/ subtracting their coefficients.

(a)

$\sqrt{3}$ (7 - 2 + 1 - 3)

= $\sqrt{3}$ (3)

= 3 $\sqrt{3}$

(b)

$\sqrt{7}$ (5 + 4 - 8)

= $\sqrt{7}$ (1)

= $\sqrt{7}$
