Question

Which step could she have used instead to simplify the expression (3t)4?

Answer 1

Instead of doing what she did, she could have use power properties. Remember you can distribute powers if you have a multiplication, as following:

`\mleft(3t\mright)^4=3^4t^4`

Thus,

`\mleft(3t\mright)^4=3^4t^4\rightarrow(3t)^4=81t^4`
