...; therefore v/3" = 3 ; ^5a = 5. Also, since the square root of a given number may be defined to be **that number which, when multiplied by itself, will produce the given number,** therefore v/2 X \/2= 2 : so also, ^2 x ^2 x ^2 = 2. Such quantities as v/2, $2, are called Surds, or... | |

...quantity; therefore t/3 2 = 3; $5 3 =5. Also, since the square root of a given number may be denned to be **that number which, when multiplied by itself, will produce the given number,** therefore ^2x^/2 = 2: so also, ^2 x ^2 x ^2 = 2. Such quantities as 1/2, ^"2, are called Surd*, or... | |

...split up into the two equal factors 3 and 3. The number 3 is therefore said to be the square root of 9. **The square root of any number is that number which, when multiplied by itself, will produce the** first number. The square root of 25 is 5, because 5X5 = 25; the square root of 49 is 7, because 7X7=49;... | |
