(I WILL MARK U AS THE BRAINLIEST)
​

Answer 1

Answer:

Step-by-step explanation:

Q1

1/7-2root3$= \frac{1}{7-2\sqrt{3} } * \frac{7+2\sqrt{3} }{7+2\sqrt{3} } \\= \frac{7+2\sqrt{3} }{(7^{2}) - (2\sqrt{3}^{2} ) } \\= \frac{7+2\sqrt{3} }{49 - (4*3)}\\\\= \frac{7+2\sqrt{3} }{49-12}\\\\= \frac{7+2\sqrt{3} }{37}$

Same way answer the second question ..pls it took lot of time for me to type this answer so plese mark it the brainliest answer
