The notation in its current form isn't entirely clear.
Did you mean to write ? The 4 isn't in the square root.
If so, then the expression is in simplest form because we cannot simplify any further (note how 10 doesn't have any perfect square factors other than 1).
Also, the 3/4 portion is fully reduced already.

Or,
Did you mean to write ? This time the 4 is inside the square root.
If so, then we can simplify like this
This means that
Answer:
x = 56
Step-by-step explanation:
Since two sides of the triangle have the same length, we knows it's isosceles. This means we we will have two base angles with the same value. Since x is the angle in between both legs, we knows x is the vertex angle.
62 is a base angle, which means the other base will be 62 as well. And since the angles of a triangle always add up to 180,
x = 180 - (62 + 62)
x = 180 - 124
x = 56
