I will mark the proper answer as brainiest​

Answer 1

Step-by-step explanation:

$\sqrt{45} - 3 \sqrt{20} + 4 \sqrt{5} \\ \blue{\mathfrak{\large{ \rightarrow \: To \: add \: or \: subract \: the \: values}}} \\ \blue{\mathfrak{\large{ firstly \: make \: the \: root \: equal.}}} \\ = \sqrt{ \underline{3 \times 3} \times 5} - 3 \sqrt{ \underline{2 \times 2} \times 5} + 4 \sqrt{5} \\ = 3 \sqrt{5} - 3 \times 2 \sqrt{5} + 4 \sqrt{5} \\ = 3 \sqrt{5} - 6 \sqrt{5} + 4 \sqrt{5} \\ = \sqrt{5} \\ \red{\mathfrak{\underline{\large{hope \: it \: helps \: you }}}} \\ \blue{\mathfrak{\underline{\large{mark \: me \: brainliest}}}}$
