Question

Answer any questions plss i will give u brainliest answer

Answer 1

Answer:

$2. \: 7 \sqrt{2} - 2 \sqrt{3}$

$3. \: (5 + \sqrt{8}) + (3 - \sqrt{2}) - (6 + \sqrt{2} ) \\ = (5 + 2 \sqrt{2}) + (3 - \sqrt{2}) - (6 + \sqrt{2} ) \\ = (5 + 3 - 6) + (2 \sqrt{2 } - \sqrt{2} - \sqrt{2} ) \\ = (8 - 6) + (2 \sqrt{2 } - 2\sqrt{2} ) \\ = 2 + 0 = 2$

$4.true$

$6. \: irrational \: number$

$7. \: ( 3 + \sqrt{2} ) \: ( 4 + \sqrt{3} ) \\ = (12 + 3\sqrt{3} + 4 \sqrt{2 } + \sqrt{6} )$

$8 .\frac{4 \sqrt{28} }{3 \sqrt{7} } \\ \frac{4}{3} \times \sqrt{4 } = \frac{4\sqrt{4} }{3}$

Answer 2

Answer:

4: true

Step-by-step explanation:

0 is a rational no. because it can be written in the form of 0/1 where 0 and 1 are integers and denominator is not equal to 0
