Convert decimal to fraction
a^2+(21/10)^2=2.9
Use exponent rules
a^2+441/100=2.9
Move constant to the right
a^2=2.9-441/100
Calculate
a^2=-151/100
This equation has no solution.

<h3>What is meant previewing a test?</h3>

In order to find the various problem kinds and their point values during the test preview, you must read the complete test. Mark the questions that you can answer quickly and easily.

The benefits of previewing the test are-

  • You will probably be given credit for the answers even if you accidentally copied them from the scratch paper.
  • Your effort on the scratch paper can earn you some points if a thoughtless mistake causes you to get the answer wrong.
  • If you do make a mistake, it will be simpler to find it when the instructor goes through the test.
  • By doing this, you can avoid making the same errors on your next exam.

Therefore, resolve each issue by re-entering the solution into the equation or performing the opposing operation needed to provide the appropriate response. Do not leave the testing room until the bell has rung or after you have gone over each problem twice.
