Answer:
try x= 4z/y
Step-by-step explanation:
The base is the number that the exponent is attached to. So ten squared, the base is ten.
Answer:

Step-by-step explanation:
<u>Similar Triangles</u>
By looking at the construction of the figure, we can safely assume both triangles are similar, i.e. their internal angles are equal and their sides are proportional. Following the proportion of the heights and bases of both triangles we can set this relationship:

Simplifying both fractions

Solving for x

The answer its “i” because there are two complex square roots of −1, namely i and −i,
