Answer:
$205.73
Step-by-step explanation:
First we find the square area,
multiply 10 by 4.5 and we get 45
we convert feet to meters by dividing it by 3.281
45/3.281=13.71533
we the multiply 13.71533 by 15 to get the total price
we get 205.72996 and round it to 205.72
P - power measured in watts
E - voltage measured in volts
I - current measured in amperes
R - resistance measured in ohms

1. P = 2000 W, E = 200 V, R = ?

2. P = 0.35 W, E = 150 V, R = ?
x³y²
For this case, the first thing you should know is the properties of the exponents.
Let's write the full fraction:
(1) / (x ^ 3 * y ^ 2)
We have that by power properties:
(1) / (x ^ 3 * y ^ 2) = x ^ -3 * y ^ -2
Therefore the equivalent numerator is:
x ^ -3 * y ^ -2
Answer:
x ^ -3 * y ^ -2
