What does leaving answer in exact form mean?

It is irrational and it is said to be “in exact form”. A decimal answer, such as 1.73 (2 decimal places), is not exact. Even 1.732050807568877 is not exact. When an answer is required in exact form, you must write it as a surd, ideally simplifying it if possible.

What does exact form mean in math?

In mathematics, especially vector calculus and differential topology, a closed form is a differential form α whose exterior derivative is zero (dα = 0), and an exact form is a differential form, α, that is the exterior derivative of another differential form β.

Is exact form the same as radical form?

In the same way numbers can have different “roots”. There is no number squared that will equal 5. Radical expressions can have an exact or an approximate answer. Exact answers will be left in radical form and approximate answers will be found with a calculator and will be a rounded decimal answer.

What does it mean simplest radical form?

Expressing in simplest radical form just means simplifying a radical so that there are no more square roots, cube roots, 4th roots, etc left to find. It also means removing any radicals in the denominator of a fraction.

What does it mean when it says in terms of pi?

This means multiply the number by itself. Multiply the product times pi. a. If you are leaving the answer in terms of pi, then you can just leave the pi symbol in the answer.

How do you write an exact answer?

If b is NOT an integer, then x cannot be written in “exact” form, except as the formula given, and you can write it only approximately as a decimal number. For example, if b= 3, we could write the “exact” solution as x = 4 3 − 7 3 \displaystyle x= \frac{\sqrt[3]{4}- 7}{3} x=334 −7 or approximately as -1.80420.

What does it mean by exact answer?

Exact value is where you cannot estimate the value you must be precise, eg; you can’t estimate something as being around about 5 centimetres; no you need an exact value such as 5.62.

What is exact simplest form?

A fraction is in simplest form when the top and bottom cannot be any smaller, while still being whole numbers. Example: 2/4 can be simplified to 1/2. To simplify a fraction: divide the top and bottom by the greatest number that will divide both numbers exactly (they must stay whole numbers).
