ABC is an isoscele triangle in which [AB]=[AC]=5cm and [BC]=6cm. Calculate [AM], where M is the mid-point of BC.

In order to find the length of [AM], you want to look at only half of this triangle. Half of an isosceles triangle is a right angle triangle! Therefore you can use Pythagorean theory:
a^2 + b^2 = c^2 (hypotenuse)
Do you think you can solve this from here?
