Question

Raiz quadrada de 169+ raiz quadrada de 1,69 = ?
Preciso do Cálculo!!

Answer 1

$\sqrt{169} = 13 \sqrt{1,69} = 1,3$

13*13= 169
1,3*1,3= 1,69

Answer 2

169|13
 13| 13
   1

169 = 13²
√169 = √13² = 13

1,69 = 169 × 10⁻²

$\sqrt{169\times10^{-2}} \\ \\ \sqrt{169} \times10^{\frac{-2}{2}} \\ \\ 13\times0,1 \\ =1,3$

Então:

13 + 1,3 = 14,3
