Math Problem Statement

Express the equation in logarithmic form: (a) 4^5 = 1024 is equivalent to log_4 A = B. (b) 10^-2 = 0.01 is equivalent to log_10 C = D.

Solution

The problem is asking to convert exponential equations into logarithmic form. Let's go through each part.

Part (a)

The given equation is: 45=10244^5 = 1024 In logarithmic form, an equation ax=ba^x = b can be written as logab=x\log_a b = x.

Applying this to 45=10244^5 = 1024: log41024=5\log_4 1024 = 5 So:

  • A=1024A = 1024
  • B=5B = 5

Part (b)

The given equation is: 102=0.0110^{-2} = 0.01 Applying the same logic, we can rewrite 102=0.0110^{-2} = 0.01 as: log100.01=2\log_{10} 0.01 = -2 So:

  • C=0.01C = 0.01
  • D=2D = -2

Summary of Answers

  • (a) A=1024A = 1024, B=5B = 5
  • (b) C=0.01C = 0.01, D=2D = -2
