Answer 1

$\huge\underline\mathrm\red{Square\:root:-}$

To find the square root of a number, you want to find some number that when multiplied by itself gives you the original number. In other words, to find the square root of 25, you want to find the number that when multiplied by itself gives you 25. The square root of 25, then, is 5. The symbol for the square root is equation. Following is a partial list of perfect (whole number) square roots.

Take for example the number 5.

If you multiply this twice. i.e. 5 x 5 = 25.

25 is called the square of 5, and 5 is called the square root of 25.

Similarly, 8 x 8 = 64. So, 64 is called the square of 8, and 8 is called the square root of 64.

If no sign (or a positive sign) is placed in front of the square root, the positive answer is required. No sign means that a positive is understood. Only if a negative sign is in front of the square root is the negative answer required. This notation is used in many texts, as well as this book.

$\huge\underline\mathrm\red{Cube\:root:-}$

To find the cube root of a number, you want to find some number that when multiplied by itself twice gives you the original number. In other words, to find the cube root of 8, you want to find the number that when multiplied by itself twice gives you 8. The cube root of 8, then, is 2 because 2 × 2 × 2 = 8. Notice that the symbol for cube root is the radical sign with a small three (called the index) above and to the left, equation. Other roots are similarly defined and identified by the index given. (In square root, an index of 2 is understood and is usually not written.) Following is a partial list of perfect (whole number) cube roots.

Take the number 7.

If you multiply this thrice. i.e., 7 x 7 x 7 = 343.

343 is called the cube of 7, and 7 is called the cube root of 343.

Similarly, 9 x 9 x 9 = 729. So, 729 is called the cube of 9, and 9 is called the cube root of 729.
