please help.

I also has a similar problem which is (3/2b^4)^3
But for this one, since it is a positive exponent, (i don't do well with negatives)
can someone please guide me through what i have to do WITHOUT giving me the answer, BC i wanna try this on my own, but don't know where to start.
To simplify the first one you need to get rid of the outside exponent. You multiply 3/5 by 2. (You flip the fraction and that gets rid of the negative.)
Then you simply multiply 4 and -2.
Don't forget to keep the y!

For the second one, you multiply 3/2 by 3 and then multiply 4 by 3.
Don't forget the b!

Let me know if that helps at all.😀
It did! Thanks a bunch!
