Question

ratoinalize the dinominator of the following 1/(√7-√6)​

Answer 1

Step-by-step explanation:

$\sqrt{7 + \sqrt{6 \div 1} }$

is your answer

Answer 2

• rationalize the denominator of the following 1/(√7-√6)

=1/(√7 - √6) x (√7 + √6) / (√7 + √6)

= (√7 + √6) / (√7 - √6)(√7 + √6)

We need to apply the formula (a - b)(a + b) = a^2- b^2in the denominator

=(√7 +√6) / (√7)^2 - (√6)^2

= (√7 + √6) / 7 - 6

= (√7 + √6) /1

= (√7 + √6)
