√144 = √122 = 12
This is a difficult one to answer without being able to use math type. You have to multiply the top and bottom of this expression by the conjugate to solve the problem. But since I can't show you that, I will just give you the answer without the work included.The numerator is a-2sqrt(ab)+bThe denominator is a-bI will solve all your math problems. Check my profile for more info.
It is an irrational number and rounds to 5.66 to the nearest hundredths
square it and cube it

The square root of 64 is 8 and you can work it out using the square root algorithm.
By using the quadratic equation formula which will work out as: x = 4- the square root of 32 and x = 4+the square root of 32
The square root of 49 is 7 so each side of the square measures 7 centimeters
1.2. If you want to solve this with calculator, you can square root 1.44. Alternatively you can think about what by itself is 144 and work back

It is actually impossible to work out the square root of a shape but you can work out the square roots of the interior and exterior angles, the area and the perimiter
square it and cube it
(4/4)-(the square root of 4)-(the square root of 4)
