2. A company produces wires with mean resistance 1 ohm and standard deviation 0.03 ohms. A wire is considered good, if its resistance falls between 0.97 and 1.03. An electrical engineer is building a circuit that needs 7 of these wires. The engineer purchases 8 wires; the extra one is to secure the success of the project. (i) What assumption can you make about the distribution of the re- sistance of a wire? (ii) What is the probability that the engineer will be able to build the circuit?

Power Operation

Power operation is topic of algebra in Math. It is use to represent repeated multiplication. Very big number and very small number can be easily express using power operation. Power operation is useful in many fields. In space engineering, it helps in representing the distance or size of particular heavenly body. In medical field, it is used to represent very small size. In medical field it helps to mention size of bacteria or virus. 

Exponents

The exponent or power or index of a variable/number is the number of times that variable/number is multiplied by itself.
