Jika nilai dari log 3 = 0,4771 maka nilai dari log √18 + log 6 - log 2√2 =

log√18 + log 6 - log 2√2= log (3√2 . 6 / 2√2) = log 9 = 2xlog 3 = 2x0.4771=0.9542

[tex] log(3) = 0.4771 \\ nilai \: log \: \sqrt{18} + log(6) - log(2 \sqrt{2} ) = \\ = log( \sqrt{18} \times 6) - log(2 \sqrt{2} ) \\ = log(6 \sqrt{18} ) - log(2 \sqrt{2} ) \\ = log( \frac{6 \sqrt{18} }{2 \sqrt{2} } ) \\ = log( \frac{6 \sqrt{9 \times 2} }{2 \sqrt{2} } ) \\ = log( \frac{6 \sqrt{9} \times \sqrt{2} }{2 \sqrt{2} } ) \\ = log( \frac{6 \sqrt{9} }{2} ) \\ = log(3 \sqrt{9} ) \\ = log(3 \times 3) \\ = log(9) \\ = log(3) + log(3) \\ = 0.4771 + 0.4771 \\ = 0.9542 \\ semoga \: membantu [/tex]
