Is this the same organic side chain?

Attached is the image of the desired structure, my question is based on what is pictured as (CH3)2HC- I represented this group as C3H7 which does seem like the logical equivalent, but just being safe here. Am I right?

Thank you!

(CH₃)₂CH- is what would be called isopropyl, C₃H₇- is ambiguous as it can be both isopropyl and n-propyl.

Ah! Okay, But I'm just an international baccalaureate student if you know what that is, would they expect so much?!

Much? I would expect high school students to understand the ambiguity, after all this is a very basic isomerism and judging from the picture the question is about isomerism as well.
