Question

calcule a expressao algebica com radicais A) 10∛2+5√3-2√3+4∛2 B)∛2x+3√3y-8y3y+12∛2x-4∛2x

Answer 1

Resposta:

$a)10 \times 2 + 5 \sqrt{3} - 2 \sqrt{3} + 4 \times 2 = \\ 20 + 5 \sqrt{3} - 2 \sqrt{3} + 8 \\ 28 + 3 \sqrt{3} \\ \\ b)2x + 3 \sqrt{3y} - 8y \times 3y + 12 \times 2x - 4 \times 2x \\ 2x + 3 \sqrt{3y} - 24 {y}^{2} + 24x - 8x \\ 18x + 3 \sqrt{3y} - 24 {y}^{2}$
