The above is a simple math problem and the answer to x which is the unknown is -6.5 approximately.
<h3>What is the calculation for the above answer?</h3>First, lets rewrite the word problem:
-1.96321 and - √(x) = 5
Note that "and" is also multiplication in math.
Hence,
-1.96321 * - √(x) = 5
- √(x) = 5/-1.96321
-x = (5/-1.96321)²
- x = 6.48644131993
x = - 6.48644131993
x -6.5
