Question

2√2-2√3 solve this please

Answer 1

Answer:

Using the rule: (a+b) (a-b) = a^2 - b^2

Our equation: (2+sqrt3) (2-sqrt3) = 2^2 - sqrt3^2

= 4 - 3 = 1

Notes:

1.1 The definition of square root:

sqrt(n) * sqrt(n) = n.

This is by the definition of square root:

…. If r = sqrt(n)

…. then r X r = n.

1.2 Any n which is a result of squaring - is necessarily a positive number.
