Did I do these right?
Simplify:
129. Sqrt. y^14
y^7
131. - Sqrt. a^6
-a^3
141. Cubed Rt. 125b^15
125b^5
Before I continue, I want to make sure, firstly, that I understand what I'm doing and, secondly, that I'm distributing the fractions properly. For example:
Cubed Rt. 125b^15
I multiplied 1/3 and 15 and got 5. Should I have distributed 1/3 to the 125, too? ...Assuming I'm doing all this right...
