Question

$\sqrt{45} + \sqrt{245 } - \sqrt{500} + \sqrt{625 }$
​

Answer 1

Answer:

$\sqrt{45} + \sqrt{245} - \sqrt{500} + \sqrt{625} \\ \sqrt{3 \times 3 \times 5} + \sqrt{5 \times 7 \times 7} - \sqrt{5 \times 10 \times 10} + \sqrt{25 \times 25} \\ 3 \sqrt{5} + 7 \sqrt{5} - 10 \sqrt{5} + 25 \\ 10 \sqrt{5} - 10 \sqrt{5} + 25 \\ 25$
