$\sqrt{50}+ \sqrt{18}- \sqrt{8}$

Answer 1

$\sqrt{50} + \sqrt{18} - \sqrt{8} = \\ = \sqrt{2 \times {5}^{2} } + \sqrt{2 \times {3}^{2} } - \sqrt{2 \times {2}^{2} } = \\ = 5 \sqrt{2} + 3 \sqrt{3} - 2 \sqrt{2} = \\ = (5 + 3- 2) \sqrt{2} = 6 \sqrt{2}$

Answer 2

Boa tarde

√50 + √18 - √8

= √(25*2) + √(9*2) - √(4*2)
= 5√2 + 3√2 - 2√2 
= 6√2 ou 8.4853
