Evaluate square root of 0.4 correct upto two places of decimal<\/p>\n\n\n\n

The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n

To evaluate the square root of 0.4 up to two decimal places, follow these steps:<\/p>\n\n\n\n

    \n
  1. Understanding the square root<\/strong>: The square root of a number xx is a number yy such that y2=xy^2 = x. For 0.4, we need to find the number whose square is 0.4.<\/li>\n\n\n\n
  2. Using a calculator<\/strong>: The most straightforward way to calculate the square root of 0.4 is by using a scientific calculator or a mathematical software tool. When you enter 0.4\\sqrt{0.4}, the result is approximately 0.632455532.<\/li>\n\n\n\n
  3. Rounding the result<\/strong>: Since we are asked to round the answer to two decimal places, the result becomes 0.63<\/strong>.<\/li>\n\n\n\n
  4. Verification<\/strong>: To check if this is correct, square the rounded result. That is, calculate (0.63)2(0.63)^2, which equals 0.3969. This is close to 0.4, showing that 0.63 is a reasonably accurate approximation.<\/li>\n\n\n\n
  5. Importance of rounding<\/strong>: In many real-world applications, values are rounded to a specific number of decimal places for simplicity or due to the precision of measuring instruments. In this case, rounding to two decimal places provides a good balance between accuracy and ease of use.<\/li>\n<\/ol>\n\n\n\n

    Conclusion<\/strong>: The square root of 0.4, correct up to two decimal places, is 0.63<\/strong>. This value is rounded from the more precise answer of 0.632455532.<\/p>\n","protected":false},"excerpt":{"rendered":"
