Question

√50-√98+√162 simplfy step by step​

Answer 1

√98 or 7√2

Step-by-step explanation:

only we have to solve by simplifying

i.e.

$\sqrt{50} - \sqrt{98} + \sqrt{162} = \sqrt{25 \times 2} - \sqrt{49 \times 2} + \sqrt{81 \times 2}$

so,

$= \sqrt{ {5}^{2} \times 2} - \sqrt{ {7}^{2} \times 2} + \sqrt{ {9}^{2} \times 2}$

$= 5 \sqrt{2} - 7 \sqrt{2} + 9 \sqrt{2}$

$= 7 \sqrt{2}$

OR

$= \sqrt{98}$
