Answer 1

Answer:

$\sqrt{49} + \sqrt{0.49} + \sqrt{0.0049} \\ = 7 + \sqrt{ \frac{49}{100} } + \sqrt{ \frac{49}{10000} } \\ = 7 + 0.7 + 0.07 \\ = 7.77$

Here is your solution. Thanks

Answer 2

Answer:

$\sqrt{49} = 7 \\ \\ \sqrt{49} + \sqrt{.49} + \sqrt{.0049} = \sqrt{49} + \sqrt{49 \div 100} + \sqrt{49 \div 10000} = 7 + 0.7 + 0.07 = 7.77$
