A material with higher refractive is more optically dense than a material with lower refractive index. Primary Index is an ordered file which is fixed length size with two fields. Related. Such homomorphic representatives (morphological equivalents, see Chapter XXV) may thus serve as indices of a given horizon even where intercommunication has not occurred. But, remember that 0 0 1. 4 3 is the index form (or power form) of 64; 4 4 4 is the expanded form of 64; For 64 = 4 4 4 = 4 3, the base number 4 appears three times as a factor of the basic numeral (or number) 64; 4 3 is read as '4 to the power 3' or simply '4 cubed' Example 2. Also, the answer key and explanations are given for the same. Since the power is positive, it is a positive index. Solution: The index of 15 is 2 and we have 1 as the power of the radicand. There are a number of important rules of index numbers: y a y b = y a+b Examples 2 4 2 8 = 2 12 The two basic laws of indices are: \[{a^m} \times {a^n} = {a^{m + n}}\] \[{a^m} \div {a^n} = {a^{m - n}}\] Try to use these to work through the example questions below. itive indices.
