$= \frac{8}{9}$ $= 8/9$

For multiplication and division involving roots, you can find the roots separately.

So $\sqrt{\frac{64}{81}} = \frac{\sqrt{64}}{\sqrt{81}}$ $sqrt(64/81) = sqrt64/sqrt81$

$= \frac{8}{9}$ $= 8/9$

However for addition and subtraction you have to work with the terms as they are given

$\sqrt{16 + 9} is not the same as \sqrt{16} + \sqrt{9}$ $sqrt(16 + 9) " is not the same as " sqrt16 +sqrt9$

$= \sqrt{25} = 4 + 3$ $= sqrt25 " "= 4 + 3$

$= 5 = 7$ $= 5 " "= 7$
