Question

Calcule:

a) 10√4
b) 3 +√25
c) 1 -√4/9
d) √100 -√25

Answer 1

$A)\\ \\ 10\sqrt{4} \\ \\ 10.2 => 20\\ \\===\\ \\ B) \\ \\ 3 + \sqrt{25} \\ \\ 3 + 5 => 8\\ \\ ===\\ \\ \\C) \\ \\1- \sqrt{\dfrac{4}{9}} \\ \\\\ 1 - \dfrac{2}{3}\\ \\\\ => \dfrac{1}{3} \\ \\ ===\\ \\ \\D) \\ \\ \sqrt{100} - \sqrt{25} \\ \\ 10 - 5 => 5$
