Answer

2a+b\mathbf{2a + b}

Step-by-step solution

4 steps
  1. Rewrite log⁡1012\log_{10} 12 using prime factorization.

    log⁡1012=log⁡10(22×3)\log_{10} 12 = \log_{10} (2^2 \times 3)
  2. Apply the logarithm product rule, log⁡(xy)=log⁡x+log⁡y\log (xy) = \log x + \log y.

    log⁡10(22×3)=log⁡10(22)+log⁡103\log_{10} (2^2 \times 3) = \log_{10} (2^2) + \log_{10} 3
  3. Apply the logarithm power rule, log⁡(xn)=nlog⁡x\log (x^n) = n \log x.

    log⁡10(22)+log⁡103=2log⁡102+log⁡103\log_{10} (2^2) + \log_{10} 3 = 2 \log_{10} 2 + \log_{10} 3
  4. Substitute the given values, log⁡102=a\log_{10} 2 = a and log⁡103=b\log_{10} 3 = b.

    2log⁡102+log⁡103=2a+b2 \log_{10} 2 + \log_{10} 3 = 2a + b

    The expression for log⁡1012\log_{10} 12 in terms of aa and bb is:

    2a+b\mathbf{2a + b}
