the bottom one
Step-by-step explanation:
They are both the same ab and bc but im not entirely sure
- i =

- Product rule of radicals: √ab = √a x √b
Firstly, factor out i: 
Next, apply the product rule of radicals here as such:

<u>Your answer is 5i√2, or the second option.</u>
10 is the answer. Hope that helped
Answer:

Step-by-step explanation:
Given
See attachment for model
Required
Determine
from the model
The model is represented by:

To get:
, we consider the first partition
The number of shaded box is 63 ---- this represents the denominator
The total boxes shaded at the bottom is 36 ---- this represents the numerator
So, we have:

To get:
, we consider the first partition
The number of shaded box is 63 ---- this represents the denominator
The total boxes shaded at the bottom is 16 (do not count the gray boxes) ---- this represents the numerator
So, we have:

The equation becomes:
