Question

Simplify :
1/3-2√7 - 1/2√2-√7

Answer 1

Answer:

The value of expression is - 8.311  .

Step-by-step explanation:

Given as :

The expression is written

$\dfrac{1}{3}$ - 2 $\sqrt{7}$ - ($\dfrac{1}{2}$ × $\sqrt{2}$) - $\sqrt{7}$

or, $\dfrac{1}{3}$ - 2 $\sqrt{7}$ - ($\dfrac{\sqrt{2} }{2}$) - $\sqrt{7}$

or, $\dfrac{1}{3}$ - 2 $\sqrt{7}$ - ($\dfrac{1}{\sqrt{2} }$) - $\sqrt{7}$

or. $\dfrac{1}{3}$ - ($\dfrac{1}{\sqrt{2} }$) - $\sqrt{7}$ - 2 $\sqrt{7}$

or. $\dfrac{1}{3}$ - ($\dfrac{1}{\sqrt{2} }$)  - 3 $\sqrt{7}$

or, 0.333 - 0.707 - 7.937

or, -8.311

So, The value of expression = - 8.311

Hence,The value of expression is - 8.311  . Answer
