The GCF is 3y^2.
The GCF is 2x.
The GCF is 4.
The GCF is 7mn.
(a+b)(a squared-ab+b squared)
5 squared is 25, and 6 squared is 36. So the square root of 30 has to be between 5 and 6. Since 30 is fairly close to midway between 25 and 36, 5.5 would be a reasonable estimate. (My calculator tells me that the answer is approximately 5.477, so 5.5 is quite good.)
the easiest thing to know it A squared + B squared = C squared
A^2 + B^2 = C^2 Side A squared plus Side B squared has to equal Side C squared
Because 6 squared = 36
Deductive reasoning, trial and error. The square root of 500 will be between 22 and 23, closer to 22. 22.3 squared is 497.29 22.36 squared is 499.97
The hypotenuse of a right angle triangle when squared is equal to the base squared plus the height squared and the formula is usually given as:- a2+b2 = c2 whereas a and b are the base and height respectively and c being the hypotenuse which is the largest side
Pythagoras' theorem states that for any right angle triangle its hypotenuse when squared is equal to the sum of its squared sides.
Any number, squared, is the number multiplied by itself. So 142 = 14*14. And that, is 196.
Deductive reasoning, trial and error. The square root of 78 will be between 8 and 9, closer to 9. 8.7 squared = 75.7 8.8 squared = 77.4 8.9 squared = 79.2 8.8 is the closest without going over.
For a square, the area is always 1/4 of the perimeter squared. Or one side squared.
