An easier way of doing it, Differentiate the top and the bottom, (2z +2)/(4z^3) = 6/32 when z=2

Shouldn't the first problem work out to 6/32 rather than 6/12?

I had the exact same problem as the fisrt one in a homework, and I did the same mistake xD

@rhymenorreasonable Sure. The square root of 1 is equal to 1, so, in the denominator, you end up with 1 + 1. Which is equivalent to 2. So, the numerator remains a constant 4, and the denominator adds up to 2. So you end up with 4/2. Does that help any?
