Recall that exponents are a way of representing repeated multiplication. For example, the notation 54 can be expanded and written as 5 • 5 • 5 • 5, or 625. And don’t forget, the exponent only applies to the number immediately to its left, unless there are parentheses.
What happens if you multiply two numbers in exponential form with the same base? Consider the expression (23)(24). Expanding each exponent, this can be rewritten as (2 • 2 • 2) (2 • 2 • 2 • 2) or 2 • 2 • 2 • 2 • 2 • 2 • 2. In exponential form, you would write the product as 27. Notice, 7 is the sum of the original two exponents, 3 and 4.
What about (x2)(x6)? This can be written as (x • x)(x • x • x • x • x • x) = x • x • x • x • x • x • x • x or x8. And, once again, 8 is the sum of the original two exponents.

The ratio of the model's height to actual height of tower is 1:725
Step-by-step explanation:
Given
Actual height of Sears Tower = 
= 1450 feet
Height of Model = 
= 24 inches
We can divide the actual height by the model's height to find the scale
Let z be the ratio of the height of the model to the actual height
The ratio should be in same unit.
We know that
1 ft = 12 inches
Then
Hence,
The ratio of the model's height to actual height of tower is 1:725
