Question 624205: Can you help me solve this problem please?
In () I have the following fraction, ((12x^-3)(z^4)/3xz^-4)^-3
If it were a word problem I would read it as, open parentheses, twelve x to the negative three power, z to the fourth power, divided by three x z to the negative four power, close parentheses to the negative three power.
I'm unsure how to start the problem. Can I cancel the 12x^-3 and 3x^2? Or do I have to immediately move the 12x^-3 to the denominator because its a negative exponent?
