Question

Evaluate c2 + a if a = 1/2 and c=9

Answer 1

Exact form : 37/2
Decimal form : 18.5
Mixed number Form : 18 1/2
I’m guessing the answer would be all of these above but mainly 37/2.

Answer 2

Explanation:

I assume that you mean c squared o+ 1/2, but without brackets, there are all sorts of possibilities. I'll do the one I think it is first.

c^2 + a

9^2 + 1/2

81 + 1/2

81.5

But it could also be

2* 9 + 1/2

18 1/2

18.5

And to make things worse, it could be

9^( 2 + 1/2)

9^(2.5)
