The volume of any prism is given by
.. V = Bh . . . . B is the area of the base, h is the height
You have
.. 300 = B*3
.. 300/3 = B = 100
The area of the base is 100 square units.
Step-by-step explanation:
factor sin(x) out of the equation
sin(x) * (
) = sin(x)
Use the trigonometric identity 
sin(x) * 1 = sin(x)
sin(x) = sin(x)

Here, we want to get what Andre's mistake was and correct it
To answer this, we are supposed to use the division law of indices
We have this as;

Now, in the case of this question, x is 4 and y is -3
So, we have the expression as;

His mistake is thus adding the exponents instead of subtracting
