30+2+0.8+0.09+0.007
Step-by-step explanation:
The above is the correct answer, however if you are looking for it is exponential form here is it!
= 3 × 10^1 + 2 × 10^0 + 8 × 10^-1 + 9 × 10^-2 + 7 × 10^-3
Answer:
The (y^2 ) or (y^–2) It is not clear, I solved it in both ways (y^2) and (y^-2) .^_^

Step-by-step explanation:
We have this function and let's derive it in terms of x.
y =x^2/In x
Dy/Dx=(x^2/In x)'=2/lnx *(x^2)'-(x^2/In x)'=> 2
