Question

root 7 minus 1 divided by root 7 + 1 - root 7 + 1 by root 7 minus 1 equal to a + b root 7 find the value of a and b ​

Answer 1

Answer:

$\frac{ \sqrt{7} - 1 }{ \frac{ \sqrt{7} + 1}{ \sqrt{7} - 1 } } = a + b \sqrt{7}$

=

$- 22 + 7 \sqrt{7 \: } \: \: .....answer$

$a = - 22 \: and \: b = 7$

Step-by-step explanation:

rationalize the Fraction.....

》

$\frac{ { \sqrt{7} - 1}^{2} }{ \sqrt{7} + 1 } = \frac{ { \sqrt{7} - 1}^{2} \times \sqrt{7} + 1 }{7 - 1} = \frac{ { \sqrt{7} - 1}^{3} }{6 }$

= -22 +7 root7

》 a= -22 & b =7
