Question

Calcule o valor da expressão : (10 √27 + 10√3) : 10√3

Answer 1

$\boxed{\frac{10 \sqrt{27} +10 \sqrt{3} }{10 \sqrt{3} }=\frac{20 \sqrt{3}+10 \sqrt{3} }{10 \sqrt{3} }=\frac{30 \sqrt{3} }{10 \sqrt{3} }=3}$

Answer 2

10.√27+ 10.√3= 10.√9.3+10√3 = 10.3√3 + 10.√3 = 30√3 + 10√3 = 40√3
40√3 : 10√3 = 40 : 10 ( pois cortam-se as raizes) = 4
