Question

{ this means means square root

How do you solve these kind of radicals:
1. (5-{14)*(3-{2)


2. (4{2+2)*(3{3-1)


Can someone show me how to do these correctly please ?

Answer 1

1. (5-{14)*(3-{2)
I read that as
(5 - √14)(3 - √2)
= 15 - 5√2 - 3√14 + √28
= 15 - 5√2 - 3√14 + 2√7

2. (4{2+2)*(3{3-1) is it..
(4√2 + 2)(3√3 - 1) ??
= 12√6 - 4√2 + 6√3 - 2

Answer 2

Yes.

Thank You very much.
