10*10 = 100 so I would not need to estimate it! The answer is -10 or +10
Estimating is not needed, either the equation is wrong or right!A square root is a number times by itself:10 x 10 = 100
Best estimate: $100 MILLON!
98 is 100 and 63 is 60
500/5 = 100
Square, or second power. Example: 102 = 10 x 10 = 100 (10 squared, or the square of 10, or ten to the second power is equal to 100).
To heat a room of 100 square feet, approximately 10,000 watts of power are required.
The best estimate is, obviously, the exact answer which is 671898.4556 : anything else is less than best.A respectable estimate is 4000*175 = 4000*(7/4)*100 = 1000*(7)*100 = 700000.
You don't need to estimate when you can get the exact answer: 19*26/100 = 4.94
The cost to power wash 90 square feet can vary depending on the service provider and location. On average, you can expect to pay anywhere from $100 to $200 for power washing a 90-square-foot area. It's best to get quotes from multiple companies to find the most competitive price.

To square root decimals without a calculator, first convert the decimal into a fraction. For example, the square root of 0.64 can be expressed as √(64/100), which simplifies to √64/√100 = 8/10. Then, simplify the fraction to find the square root. Alternatively, you can estimate by finding the nearest perfect squares and refining your estimate through averaging or by using the long division method for square roots.
