Answer:5 sqrt2.Step-by-step explanation:sqrt8= sqrt4 * sqrt2 =2 sqrt2sqrt18= sqrt9 * sqrt2 =3 sqrt2So simplifying:

5sqrt 8 – sqrt18 – 2 sqrt2= 5*2sqrt2 – 3 sqrt 2 – 2 sqrt2

= 10 sqrt2 – 5 sqrt2

=

5 sqrt2(answer).For this case we must simplify the following expression:

Rewriting we have:

We have that by definition of properties of roots and powers it is fulfilled:

So:
