simplify (question is given above in the picture)

Answer 1

Hope u like my process
======================
1)
$2 \sqrt{50} + 3 \sqrt{32} + 4 \sqrt{18} \\ = 2 \sqrt{ {5}^{2} \times 2 } + 3 \sqrt{ {4}^{2} \times 2} + 4 \sqrt{ {3}^{2} \times 2} \\ = 2 \times 5 \sqrt{2} + 3 \times 4 \sqrt{2} + 4 \times 3 \sqrt{2} \\ = 10 \sqrt{2} + 12 \sqrt{2} + 12 \sqrt{2} \\ = 34 \sqrt{2}$

2)
$\sqrt[4]{16} - 6 \sqrt[3]{343} + 18 \sqrt[5]{243} - \sqrt{196} \\ = \sqrt[4]{ {2}^{4} } - 6 \sqrt[3]{ {7}^{3} } + 18 \sqrt[5]{ {3}^{5} } - \sqrt{ {14}^{2} } \\ = 2 - 6 \times 7 + 18 \times 3 - 14 \\ = 2 - 42 + 54 - 14 \\ = 0$
3)

Can't be clearly seen!!

Hope this is ur required answer
