Answer 1

Answer:

7.77

Explanation:

$\sqrt{49} + \sqrt{0.49} + \sqrt{0.0049}$

$= \sqrt{7 \times 7} + \sqrt{ \dfrac{49}{100} } + \sqrt{ \dfrac{49}{10000} }$

$= 7 + \sqrt{ \dfrac{7 \times 7}{10 \times 10} } + \sqrt{ \dfrac{7 \times 7}{100 \times 100} }$

$= 7 + \dfrac{7}{10} + \dfrac{7}{100}$

$= 7 + 0.7 + 0.07$

$= 7.77$
