I have to differentiate some problems using the limit definition (f(x+h)-f(x)\h), but Iam having some trouble on a couple.(adsbygoogle = window.adsbygoogle || []).push({});

1. Square root of 30 is 0 because its a constant correct?

2. R(t) = 5t^(-3/5) <---- I have tried this problem many times with the definition, but I cant come up with the correct solution and I dont know why!

Thanks
