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.

You can put this solution on YOUR website! 4x^-3) * 4z *y^-4*w^2
One error is 4x^-3. This has to be written carefully, for (4x)^-3 is very different (1/64x^3). You want 4 in the numerator/x^3 in the den.
4x^-3 *4z because divide by 2^-2 is to divide by 1/4 or multiply by 4 /y^4
x^-3 is 1/x^3
4*4 is 16
Leave the 4 alone and recognize that dividing by 2^-2 is another 4, and your numerator will be 16.
