What is an exact answer?

What is an exact answer?

As used in physics, the term “exact” generally refers to a solution that captures the entire physics and mathematics of a problem as opposed to one that is approximate, perturbative, etc. Exact solutions therefore need not be closed-form.

What does write in exact form mean?

It means that you leave your answer in the form of a fraction or radicals (square root symbol) — instead of a decimal answer.

How to simplify a radical to give an exact answer?

Start by finding the prime factors of the number under the radical.

  • Determine the index of the radical.
  • Move only variables that make groups of 2 or 3 from inside to outside radicals.
  • Simplify the expressions both inside and outside the radical by multiplying.
  • Simplify by multiplication of all variables both inside and outside the radical.

    How to find radicals on calculator?

    Enter the coefficient of the radical,index and radicand value in the input field (Example: 2 3√27)

  • Now click the button “Solve” to get the product of two radicals
  • Finally,the multiplication of two radicals will be displayed in the output field (I.e.,Multiplying Radicals,2 3√27 × 2 3√8 = 24)

    • How to solve for radicals?

    A square root (radical) of x x is a number r r whose square is: r2 = x r 2 = x r r is a square root of x

  • A cube root of x x is a number r r whose cube is: r3 = x r 3 = x r r is a cube root of x x.
  • Radical rules: an√n = a a n n = a,x√ × y√ = xy√ x × y = x y
