Given expression is .
where
Now we have to simplify this and find the next step so that negative exponent gets eliminated.
We know that when negative exponent changes sign, then it moves from numerator to denominator or from denominator to numerator as shown in the formula:
or
n has negative exponent in denominator so it will move to numerator and we get:
or
Hence final answer is .
2. The area for a circle is as follows:
A = π
The radius of the circle is 4 in, so we plug that into the equation.
A = π (4
)
4 = (4 in.)(4 in.) = 16
A = 16π
This is the area for the whole pizza, so divide that by 2 to get the area of the pepperoni
a) 8π
For the bacon, we can just divide the value we already have by 2, since it is half the area of the pepperoni
b) 4π
3. This question is asking for the circumference, whose equation is as follows:
C = 2 π r
We can use the area formula, A = π to find the radius of this circle
36π = π
Divide both sides by π:
36 =
Square root both sides:
r = 6 in.
Plug in this value to the circumference formula, C = 2 π r
C = (2)(π)(6 in.)
Your final answer is:
C = 12π in.
A = π
