For this case we have the following expression:
Rewriting the expression we have:
Where,
x: exponent to which we must raise the expression to obtain 7 as a result.
We have then:
The exponent must be equal to 1:
Clearing x we have:
Substituting valres:
Answer:
you must raise the expression to 2

We have been given a diagram. We are asked find the measure of arc EAB.
First of all, we will find the measure of arcs ED and CB using our given information.
We know that measure of an inscribed angle is half the measure of intercepted arc.
We can see that angle EBC is inscribed angle of arc EDC, so measure of arc EDC will be twice the measure of angle EBC.
Similarly, we will find the measure of arc DCB.
Therefore, the measure of arc EAB is 148 degrees and option C is the correct choice.
