Hello! I've got a math worksheet and I'm really confused on what to do on a few tricky problems. If someone could help me out with one or all of them I would really appreciate it!
The directions on my worksheet read "Use the properties of exponents to simplify each expression"
(4t^2n)(3t)^n
On this one, I first tried simply multiplying it out to get (4t^2n)[(3^n)(t^n)], but one of my classmates said this was wrong. Any ideas on what I should have done?
Also, I need a little help starting this one:
(5r-3t)^5 (3t-5r)^2 (3t-5r)
What should I do first? Factor out a GCF or first take out a negative to make them all the same? and if I do take out a negative first and then add the exponents of the like terms, is it possible to state the finished answer as -(3t-5r)^8 ?
Finally, I have no idea what to do first in this problem either:
[2(x+3y)^2]^5 {3(x+3y)^4]^3
Can I factor out a GCF first? or should i multiply the exponents together? It would be so great if someone could just get me started on these problems. Thanks!
