Question

$- 10 + \sqrt{169 } = \\ 1 - \sqrt{ \frac{4}{9} } = \\ \sqrt{ \frac{25}{36} } - \sqrt{ \frac{1}{9} } = \\ 5 \times \sqrt{ \frac{4}{100} } = \\ \\ ajudaaa$
​

Answer 1

√169 vale 13, assim fica -10+13=3

√4/9 vale 2/3, assim fica 1 -2/3= 3/3-2/3 =1/3

√25/36 vale 5/6 e √1/9 vale 1/3 = 5/6-1/3 = 5/6-2/6= 3/6 = 1/2

√4/100 vale 2/10 assim fica 5*2/10 = 10/10 = 1
