In a multiplication of two numbers, the number of significant digits in answer should equal the least number of significant digits in any one of the numbers being multiplied.
Now 5.234 has 4 significant digits while 5 is a whole number and a whole number has infinite number of significant digits.
so 5 * 5.234 =26.17000  but answer should have only 4 significant digits so correct answer is 26.17.
