Step-by-step explanation:
Answer:CD = x = 4 units
Explanation:We are given that the two triangles are similar. This means that we can set the similarity proportionality as follows:

W e have:
BC = 20 - x
AC = 20
CD = x
CE = 5
Substitute in the above proportionality and solve for x as follows:

4x = 20 - x
5x = 20
x = 4
Based on he above:
CD = 4 units
BC = 20 - x = 20 - 4 = 16 units
Hope this helps :)

ANSWER TO QUESTION 1

We rewrite to obtain;

Recall this product law of indices
we apply this law to obtain,

This simplifies to

We need to rewrite this in standard form;

We apply the product law again to get

This simplifies to

ANSWER TO QUESTION 2

We rewrite to obtain;

Recall this product law of indices
we apply this law to obtain,

This simplifies to

This is already in standard form.
