Question

Answer 1

\(1,\sqrt{4}+\sqrt{9}+\sqrt{16}+\sqrt{25}\)
\(=\sqrt{2^2}+\sqrt{3^2}+\sqrt{4^2}+\sqrt{5^2}\)
\(=2+3+4+5\)
\(=5+4+5\)
\(=9+5\)
\(=14\)
\(3,\sqrt{1}+\sqrt{9}+\sqrt{25}+\sqrt{49}+\sqrt{81}\)
\(=\sqrt{1^2}+\sqrt{3^2}+\sqrt{5^2}+\sqrt{7^2}+\sqrt{9^2}\)
\(=1+3+5+7+9\)
\(=4+5+7+9\)
\(=9+7+9\)
\(=16+9\)
\(=25\)

Answer 2

1) \(...=2+3+4+5=15\)

2) \(...=1+3+5+7+9=25\)
