The reverse square root, also known as the reciprocal square root, refers to the mathematical operation of taking the multiplicative inverse of the square root of a number. In simpler terms, it involves finding the number that, when squared, results in the reciprocal of the original number. Mathematically, the reverse square root of a number x is expressed as 1/√x or x^(-1/2).
The square root of 15 times the square root of 5 can be simplified as the square root of (15 * 5), which equals the square root of 75. The square root of 75 can be further simplified as 5 times the square root of 3. Therefore, the square root of 15 times the square root of 5 is equivalent to 5 times the square root of 3.
The square root of 225 is 15. This is because the square root of a number is a value that, when multiplied by itself, gives the original number. In this case, 15 multiplied by 15 equals 225. Therefore, the square root of 225 is 15.
