Question

1 divided root 7 - root 4 my answ. is root 7- root 4 by 3​

Answer 1

Answer:

$\frac{ \sqrt{7} }{7} - 2$

Step-by-step explanation:

The question is

$\frac{1}{ \sqrt{7} } - \sqrt{4}$

√4 = 2

We get the answer by,

$\frac{1}{ \sqrt{7} } - \frac{2}{1} = \frac{1 \times \sqrt{7} }{ \sqrt{7} \times \sqrt{7} } - \frac{2 \times 7}{1 \times 7} = \frac{ \sqrt{7} }{7} - \frac{14 }{7} = \frac{ \sqrt{7}}{7} - 2$

The answer you got was wrong.

The correct answer is

$\frac{ \sqrt{7} }{7} - 2$
