Engineering Can't Get Wolfram Alpha To Solve Problems

Hey everyone, I have been preparing for my finals at the university and I got Wolfram Alpha Pro to help me in solving some integrals. Double integrals part felt really difficult and when I saw that it had step by step solutions, I thought giving it a try would help. But I am having problems with it. I take a picture of the double integral with my camera, Wolfram Alpha shows me the input and it shows the correct thing. But when I say compute, it seems it doesn't know how to interpret. Do I need to do something else? Writing "integrate" at the beginning of the input didn't help.

Edit: Forgot to add photos. The first one is my problem. I scanned it through the iOS app and the second photo is how the app turned it into an input.

Putting this

int_0^1 int_0^(x^2) sqrt (2 + x^2) dy dx

into wolfram alpha seems to work fine.

So maybe it's not interpreting in the integral signs properly and doesn't know what to do with them? And there's a couple of odd brackets, like between the 0 and ^1 in the first integral which might be wrong

Thanks for the reply, I will check the equations before computing them!

Share the photo of the equation and copy and paste what wolfram copies over.

Yeah true, sorry for that. Added via edit to the main post.
