Answer:

Step-by-step explanation:
In order to find which expression is equivalent to
, we need to note the order of operations.
PEMDAS tells us that when solving an equation, we'd go in this order.
<em>P</em><em>arentheses</em>
<em>E</em><em>xponents</em>
<em>M</em><em>ultiplication/</em><em>D</em><em>ivision</em>
<em>A</em><em>ddition/</em><em>S</em><em>ubtraction</em>
Using this, we'd start by evaluating what's inside the parentheses,
. We'd then bring that value to the 0th power.
<em>Wait...</em> there's something special about bringing anything to the 0th power. Bringing anything to the 0th power makes the value 1.
It can be -5... it can be 1,000,000, any number possible, taken to the 0th power, will always be 1.
So no matter what the value inside the parentheses is, taking it to the 0th power will <u>always make it 1</u>.
Therefore, this expression is equivalent to 1.

Answer: 72
Step-by-step explanation:
From the question, we are informed that a disc jockey can play 7 records and that there are 9 records to select from for a particular segment of a radio show.
The number of ways that the program for the segment be arranged will be:
= 9! / 7!
= (9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1) / (7 × 6 × 5 × 4 × 3 × 2 × 1)
= 9 × 8
= 72
