GCSE Maths homework
Can anyone help with my GCSE maths homework? In the topic of powers and indices, the question is 'Evaluate 5' (for 1 mark).
The next question on the sheet is 'Evaluate 4 to the power of minus 2' which is 1/16 so the first question should be fairly straightforward as well.

5. 5 to the power of 2 =25. to the power of 3, 125

evaluate 5 ... to what? there seems to be something missing after the "5"??

Is it 5^1 - that would be 5

[Prudie]

Does it just say 5? If the answer has to be with a power/index then any number stays the same if raised to the power of 1 so
5=5 to the power of 1
If that's what you mean.

You really ought to do your own homework. If you don't understand the question, ask your teacher for clarification.

"Evaluate 5" - the literal answer is 5, but it seems more likely that there's something missing from the question.

I think the answer must be 5 to the power of 1. That makes sense if there's nothing missing.

Thank you!!

Yes 5 =5¹, although Evaluate doesn't seem the right word for the question.
Is there nothing else in the question?

4^-2 = sqrt(4) = 2

[factor-fiction]

No- - you are think of 4^½ which = square root of 4

[Ellipsis]

4^-2 = 1 / 4^2 = 1/16

[factor-fiction]

The OP already had that Ellipsis. - I was correcting KerrAvon's answer not the OP's

I was also correcting KerrAvon, showing the working ...

Thanks, sorry- maybe I'm feeling a bit sensitive today!

[KerrAvon]

yes sorry I was thinking for 4^0.5 doh!

[Ellipsis]

I hadn't even seen your answer factor30 ... one of those started to type, did something else, then finished the post moments ... :)
