Question

if x (√6-√5)(√6+√5) then what type of number is x: rational, irrational or an integer

Answer 1

it is rational number

Answer 2

Hey,

Given,

x = (√6-√5) (√6+√5)

=> It is a rational number.

EXPLANATION:-

Let √6 be a and √5 be b.

Then,

x = (a-b)(a+b)
=> x = a²-b²
=> x = (√6)²-(√5)²
=> x = 6-5=1 which is a rational number as it can be written in the form p/q where p and q are integers and q≠0.
