Tolong dijawab ya please

[tex]5 \times 2log {y}^{2} - 2logy + 4log \frac{1}{y} \\ = 5 \times 2 \times 2log2 - 2logy + {2}^{2} log {y}^{ - 1} \\ = 10 \times 2log \frac{2}{y} + ( \frac{ - 1}{2} )2logy \\ = 10 \times \frac{ - 1}{2} \times 2log \frac{2}{y} .y \\ = - 5 \times 2log2 \\ = - 5 \times 1 = - 5[/tex]



maaf kalo salah
