Answer:
When you are "multiplying" exponents, you're really just adding them together. So in the case of (x² ⋅ x⁴), you add the exponents:
2 + 4 = 6
would be the answer.
On the other hand, raising a power to a power, is actually multiplying them. So it would just be:
2 ⋅ 4 = 8
would be the answer.
The answer is:
The fabric will cost $4.58
D.$4.58
<h2>Why?</h2>Since it's a conversion exercise, we need to pay special attention to the conversion procedure.
From the statement we know that:
So, if she needs 10 feet of fabric, we need to convert it to meters, and then, calculate its cost.
We have that:
Now, we have that each meter of fabric cost $1.50, so, 3.05m of fabric will cost:
Hence, we have that the cost of the fabric will be $4.58.
The correct option is: D.$4.58
Have a nice day!
