hasil dari 10^-2 - 5^3 adalah

[tex]10 { }^{ - 2} \times 5 {}^{3} \\ = (2 \times 5) {}^{ - 2} \times 5 {}^{3} \\ = (2 {}^{ - 2}) \times 5 {}^{ - 2} \times 5 {}^{3} \\ = \frac{1}{2 {}^{2} } \times 5 {}^{ - 2} \times 5 {}^{3} \\ = \frac{1}{4} \times 5 {}^{ - 2} \times 5 {}^{3} \\ = \frac{1 \times 5 {}^{ - 2} \times 5 {}^{3} }{4} \\ = \frac{1 \times 5 {}^{ - 2 + 3} }{4} \\ = \frac{1 \times 5 {}^{1} }{4} \\ = \frac{1 \times 5}{4} \\ = \frac{5}{4} \\ = 1 \frac{1}{4} \: \: atau \: 1.25[/tex]
