Math Problem Statement

Log1/16×⁴log√3׳log100

Solution

To simplify the expression log116×4log3×3log100\log{\frac{1}{16}} \times 4 \log{\sqrt{3}} \times 3 \log{100}, we'll proceed step by step:

Step 1: Simplify Each Logarithm

  • log116\log{\frac{1}{16}}: log116=log(161)=log16=log24=4log2\log{\frac{1}{16}} = \log{(16^{-1})} = -\log{16} = -\log{2^4} = -4\log{2}

  • 4log34 \log{\sqrt{3}}: 4log3=4×log31/2=4×12log3=2log34 \log{\sqrt{3}} = 4 \times \log{3^{1/2}} = 4 \times \frac{1}{2} \log{3} = 2 \log{3}

  • 3log1003 \log{100}: 3log100=3log102=3×2log10=6log103 \log{100} = 3 \log{10^2} = 3 \times 2 \log{10} = 6 \log{10} Since log10=1\log{10} = 1, this simplifies to: 6log10=66 \log{10} = 6

Step 2: Substitute the Simplified Logs Back into the Expression

Substituting the simplified logarithms, the original expression becomes: (4log2)×(2log3)×6(-4 \log{2}) \times (2 \log{3}) \times 6

Step 3: Combine the Expression

Now, let's combine the expression: 4×2×6×log2×log3-4 \times 2 \times 6 \times \log{2} \times \log{3} 48×log2×log3-48 \times \log{2} \times \log{3}

So, the simplified form of the expression is: 48log2log3-48 \log{2} \log{3}

This is the final simplified form of the expression.
