Question

find the values of a and b if root of 7-2÷root of 7+2=a root of 7 +b​

Answer 1

Answer:

a= -4/3 ; b= 11/3

Step-by-step explanation:

$\sqrt{7 } - 2 \div \sqrt{7} + 2 = a \sqrt{7} + b \\ multiple \: with \: \sqrt{7} - 2 \: on \: numerater \: and \: denominator \: . \\ then \: ( \sqrt{7} - 2) {}^{2} \div 7 - 4 = a \sqrt{7} + b \\ 11 \div 3 - 4 \sqrt{7} \div 3 = a \sqrt{7 } + b \\ a = - 4 \div 3 \\ b = 11 \div 3$
