 Hello and welcome to the session. In this session we discuss the following question which says evaluate 0.05 whole square. Let's move on to the solution now. We need to evaluate 0.05 whole square. This is equal to 0.05 multiplied by 0.05. So we need to find the product of these two decimal numbers. So for this we multiply the two decimals without the decimal point just like we multiply the whole numbers. That is we have 0.05 multiplied by 0.05 and this is equal to 0.0025. Since we know that 5 multiplied by 5 is 25. Then next we will mark the decimal point in the product in such a way that the number of decimal places in the product would be equal to the sum of the decimal places in the given decimal. Now in the given decimal the decimal places are 2 since we have 2 digits after the decimal and so the sum of the decimal places in the two given decimals would be 4. So we will place a decimal in the product such that the decimal places in the product would be equal to 4. So we will place the decimal here because in this case the decimal places would be equal to 4. So thus we say that 0.05 whole square is equal to 00.0025 or we say that this is equal to 0.0025. So final answer is 0.0025. This completes the session. Hope you have understood the solution for this question.
