What is the value of x in the simplified power? x=

The value of x in the simplified power is 20.

Solution:

Given expression:

Step 1: Express 4 factors of

Step 2: Expand the expression

Step 3: Simplify to the exponential form

There four -2 terms and four terms.

Step 4: Evaluate the base 2 power.

Step 5: Apply the power of a power.

Using exponent rule:

So that

⇒ x = 20

The value of x in the simplified power is 20.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
