(2t^3/5t^-4)^-2 I need help in this problem
It asks to simplify the exponent but the catch is the answer must be positive exponents ant help will be appreciated greatly
You are expected to know the rule . In your problem n = 14.
Note: If you expect to get additional help then you need to be specific in what you don't understand. Making some general comment that amounts to "I don't get it" is less than helpful in knowing what further help you need.
You might benefit from going back and reviewing the index laws you have learned so far.
