Question

va roggggg (2radicla6)×(radical8+radical18)+(3radical15):(radical45-3radical20)
​

Answer 1

Răspuns:

$19 \sqrt{3}$

Explicație pas cu pas:

$(2 \sqrt{6} )( \sqrt{8} + \sqrt{18} ) + (3 \sqrt{15} ) \div ( \sqrt{45} - 3 \sqrt{20} ) =$

$2 \sqrt{6} (2 \sqrt{2} + 3 \sqrt{2} ) + (3 \sqrt{15} ) \div (3 \sqrt{15}) \div (3 \sqrt{5} - 6 \sqrt{5} )$

$2 \sqrt{6} \times 5 \sqrt{2} + (3 \sqrt{15} ) \div ( - 3 \sqrt{5} )$

$10 \sqrt{12} - \sqrt{3}$

$20 \sqrt{3} - \sqrt{3} = (20 - 1) \sqrt{3}$

$= 19 \sqrt{3}$
