$\Rightarrow (- 3 \sqrt{5})$ $color(blue)(=> (-3 sqrt5)$

$- \sqrt{45} = - \sqrt{3 \cdot 3 \cdot 5}$ $-sqrt45 = - sqrt(3 * 3 * 5)$

$\Rightarrow - \sqrt{3^{2} \cdot 5} = - {\sqrt{3}}^{2} \cdot \sqrt{5}$ $=> - sqrt (3^2 * 5) = - sqrt3^2 * sqrt 5$

$\Rightarrow - 3 \sqrt{5} \approx 6.7$ $=> - 3 sqrt5 ~~6.7$
