Can you give us an example?

Answer 3

it means that they do not want any rounding or anything, they want you to find the exact number

Answer 4

Like Pi, when they ask you to give exact value you have to give the answers in terms of pi
like if you have the answer 10pi you can't write 31.42. You have to write 10pi

Answer 5

Exact value means the exact number must be found, usually by solving an equation etc.



They are asking for a numerical expression, that is an expression that names a particular number, a numeral.
