Evaluate the expression.
a3b2c-1d
evaluate a2b2c1d
if a = 2, b = 4, c = 10, d = 15
express your answer
as a reduced fraction.

3/4 if meant

is

Step-by-step explanation:

So the expression we want to evaluate for

is

Please make sure I typed the expression and the values for the letters right.

Plug in the given values:

In the following step I said 2^3 equals 8 because 2^3 means 2*2*2.  I also got rid of the negative exponents by taking reciprocal.

In the following step I said 4^2=16 because 4^2 means 4*4.  I also wrote 10^1 as 10.

In the following step, I'm going to rewrite everything as a fraction if it isn't already a fraction.  8=8/1 and 15=15/1.

To multiply fractions, you just multiply straight across on top and straight across on bottom.

Actually performing the multiplication:

Time to reduce:

I divided top and bottom by 10 to get this.

One more time for reducing:

I divided top and bottom by 4 to get this.

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
