Question 1

Solution:

a) $ 2\sqrt{14} + 5\sqrt{14} = 7\sqrt{14} $
b) $ 5\sqrt{17} -0.8\sqrt{17} = 4.2\sqrt{17} $
c) $ 12\sqrt{6} - 5\sqrt{6} - 7\sqrt{6} = -\sqrt{6} $
d) $4.5\sqrt{3} - 0.7\sqrt{3} = 3.8 \sqrt{3} $
e) $\frac{8}{11}\sqrt{17} - \frac{5}{11}\sqrt{17} = \frac{3}{11}\sqrt{17} $
f) $1.5\sqrt{13} - 1.7\sqrt{13} - 4\sqrt{13} = -4.2\sqrt{13} $
