(b) log10(0.01) = x x= The correct answer and explanation is : Solution: We need to determine the value of ( x ) in the equation: [\log_{10}(0.01) = x] First, recall the definition of a logarithm: [\log_b(A) = C \quad \text{means} \quad b^C = A] In this case, ( b = 10 ), ( A

(a) log10(1000) = x x= The correct answer and explanation is : Solution: [\log_{10}(1000) = x]Since logarithms answer the question: “10 raised to what power gives 1000?” we rewrite it as:[10^x = 1000]We know that:[1000 = 10^3]So, we substitute:[10^x = 10^3]Since the bases are the same, we can equate the exponents:[x = 3] Thus, the
