The power of a number is the number of times it is multiplied by itself. The value for the power is called the index. For a positive index the calculation is straightforward. However, when the index is negative the result is obtained by finding the reciprocal of the index. For a negative index value the calculations are shown as a simplified fraction. If you are using a scientific calculator convert this fractional index into its equivalent decimal value. TEST YOUR UNDERSTANDING: Find some examples of very large and very small numbers that can be expressed using powers and indices. If you are associated with engineering this will be easy. Multiplying and dividing Standard Form or Index (SI) Numbers. (n1^i1 × n2^i2)/ (n3^i3 / n4^i4) From the given base numbers and index values calculate the result. Where n1 = 7.62 | i1 = 7 | n2 = 6.05 | i2 = 3 | n3 = 10.61 | i3 = 2 | n4 = 5.62 | i4 = 4. Choose Answer option: A = 2927288000 | B = 2195466000 | C = 2634559000 | D =1463644000
