A lot of the answers on this are incorrect. Or on some, the question was written wrong. Especially when you get to any section involving logarithms. You can plug in the answer and see that their answer is is incorrect and that yours is right. You can double check with peers and triple check with ai and this app is clearly incorrect on many problems especially when it comes to logarithm. Don’t get discouraged, good chance the app is wrong. I understand a couple errors, but this is many and I’ve submit a request for each but haven’t seen any changes made. Please refund due to the lack of intellectual integrity. Being how many errors you have and your reluctance to correct.
