Section 1You are required to complete this section immediately after completing the class sessions related to each question.Answer all questions and show your workings and/or explain your results.Marks will be awarded for good presentation.You may use your calculator as required.You must show your workings.QUESTION 1[7 marks]Powers and Roots: a)State three Laws of indices and provide an example of each law (5 marks)b)Simplify (1 mark)c)Evaluate (1 mark)[TYPE YOUR ANSWER HERE]a) Indices is the way of representing the large numbers into short way. Three laws which can represent indices in the better way areLaw 1: a^m * a^n = a^(m+n)This is the first law which shows that when multiplying two identical numbers with similar power, the final result will be same to the power of both exponents when they are added together. Example: 2^2 * 2^3 = 2^5Law 2: a^m / a^n = a^(m-n)Second law tells that when we divide two same numbers having different power, then the power will be subtracted. Example: 3^4 / 3^2 = 3^2Law 3: (a^m)^n = a^(m*n)The last and third law tells that if any number is having the power and that power is alsohaving the power, then to get the final result we have to multiply both the powers.Example: (4^2)^3 = 4^6b) 10^3 * 10^2= (10)^5 = 100000c) (5^3)^4 = 5^12 = 2441406253
