Here is a list, in no particular order, of the exponent rules. In this a and b are real numbers greater than 0, and n and m are any real number.
for all a
The first step is to write this thing out as a single fraction:
The next step is to work out the parenthesis. There is only one set of parenthesis, in the denominator:
Now write the denominator as negative powers of the numerator:
Now combine powers of like bases:
Now go to work on the constants. You are expected to know (or somehow figure out) that and :
Now put negative exponents in a denominator:
You do the second one and post your solution. We'll check it.
What do you mean by applying overall exponent to the numbers? I did that I think... You mean like -5 * -2/3 right? Multiply them together? That's how I got my final exponents.
For the y, it would be correct if I just added the negative sign to the exponent right?
