Square root implies that a number x has a divisor y which when multiplied by itself equals x. In other words y² = x. The decimal system (numbers up to 10) has an interesting characteristic that helps solve your problem. If you square any number (y) that begins with 1, and ends with any number of zeros, you will have a number (x) that begins with 1, and ends with twice as many zeros as y. Conversely, if you square root any number (x) that begins with 1, and ends with an even number of zeros, you will have a number (y) that begins with 1, and ends with half as many zeros as x. Since one googol is a 1 with 100 zeros after it, the square root is a 1 with 50 zeros after it, otherwise known as one hundred quindecillion.

The properties for real numbers are as follows:closure: for any numbers x and y, x + y is a real number.associativity: for any numbers x, y and z, x + (y + z) = (x + y) + z = x + y + zidentity: for any number x, there is a number, denoted by 0, such that x + 0 = x = 0 + xInvertibility: for any number x, there is a number denoted by -x such that x + (-x) = (-x) + x = 0Commutativity: for any numbers x and y, x + y = y + x.

Every mammal (of any species, including human) have two sex chromosomes, which are either "X" or "Y". (These designations come from a vague approximation of the shape of the chromosome.) These exist in EVERY CELL in the animal. If the animal has two "X" chromosomes, the animal is female; if the animal has one "X" and one "Y" chromosome, the animal is male. In every species, the female only contributes an "X" chromosome to the offspring. It is the male contribution which might be either "X" or "Y", which will determine the gender of the child.
The Yellow Rat Snake is a scary animal. It begins with the letter y.
Nothing can begin with i and x and y since only one of them can be at the beginning. The others are in second and third place.
Yefren is a town in Libya. It begins with the letter Y.
In expressions such as "x-y", both "x" and "y" can have any value. The value of "x-y" will depend on what the value of "x" and the value of "y" are.
Yemen is a country in Asia. It begins with the letter Y.
