Question 976134: (4x to the -3) (z) divided by (2 to the -2)(y to the 4)(w to the -2) = ?
The answer is supposed to be (16w squared)(z) divided by (x cubed)(y to the 4th)
For step 1, I remove the negative exponents and get: (z)/(4x cubed) divided by (y to the 4th) / (4w squared).
For step 2, I invert the denominator and multiply the following: (z)/(4x cubed) times (4w squared / (y to the 4th).
After this I'm making an error because I'm not getting to the coefficient of 16 in the numerator and 1 in the denominator.
Thank you in advance for any help.
