Σελίδα 263 - To express that the ratio of A to B is equal to the ratio of C to D, we write the quantities thus : A : B : : C : D; and read, A is to B as C to D.
Σελίδα 159 - The square root of a number is one of its two equal factors. Thus, 6 x 6 = 36 : therefore 6 is the square root of 36. The symbol for the square root is V or the fractional exponent £. Thus, -\/a, or a , indicates the square root of a, or that one of the two equal factors of a is to be found.
