How would you explain square roots: a number that is multiplied twice.
For example: the square root of 9 is 3 because 3x3=9. Three is the number that is multiplied twice to equal 9.
.
cube roots: a number that is multiplied three times. For example:
The third root of 27 is 3 because 3x3x3=27. The number (3) is multiplipied three times to equal 27.
Another example: the third root of 64 is 4 because 4 is multiplied three times to equal 64 (4x4x4=64)
.
nth roots: a number that is multiplied nth number of times to equal the radicand (the number underneath the radical sign).
.
What are some limitations of square root? the radicand must always be equal to or greater than zero (a positive number). Because squaring any number will result in a positive number. For example:
(-2)(-2)=4
and (+2)+2)=4 also.
Therefore the square root of 4 is +2 or -2.
