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
