The 2nd square number is (2^2 = 4) and the 4th cube number is (4^3 = 64). Adding these together gives (4 + 64 = 68). Therefore, the sum of the 2nd square number and the 4th cube number is 68.
You square the number in the parentheses.
Yes, it is possible to determine the square root of a negative number by using imaginary numbers. Specifically, the square root of a negative number can be expressed using the imaginary unit (i), where (i) is defined as the square root of -1. For example, the square root of -4 is written as (2i). This concept is foundational in complex number theory.
A perfect square is a rational number equal to the square of a whole number.
The square root is the number which is times by itself, to get the square number.
13th square number = 169 2nd square number = 4 169 + 4 = 173

Press 2ND and then the square root sign (above x2). Then type the number you want to find the square root of. Press ENTER to see the answer.
The number that equals the 2nd power of 49 is the square root of 49. In this case, the square root of 49 is 7, because 7 multiplied by itself (7^2) equals 49. Therefore, the number that equals the 2nd power of 49 is 7.
It is a square number but not a perfect square number.
Then the number is called a "perfect square".Then the number is called a "perfect square".Then the number is called a "perfect square".Then the number is called a "perfect square".
