NOTASI BAKU

 

\(\large \bbox [5px, border: 2px solid red]{a \times 10^{\text{n}}}\)

\(1 \leq a < 10\)

\(\text{n = bilangan bulat}\)

 

Contoh 1

\(\text{a.}\:\:\:598 000 000 = 5.98 \times 10^8\)

\(\text{b.}\:\:\:0.0000652 = 6.52 \times 10^{-5}\)

 

Contoh 2

\(\text{a.}\:\:\:30 000\text{ m} + 24000 \text{ m}\)

\(\:\:\:\:\:\:\:3.0 \times 10^4 \text{ m} + 2.4 \times 10^4 \text{ m}\)

\(\:\:\:\:\:\:\:5.4 \times 10^4 \text{ m}\)

 

\(\text{b.}\:\:\:0.00856\text{ mm}- 0.00078 \text{ mm}\)

\(\:\:\:\:\:\:\:8.56 \times 10^{-3} \text{ mm} - 7.8 \times 10^{-4}\text{ mm}\)

\(\:\:\:\:\:\:\:8.56 \times 10^{-3} \text{ mm} - 0.78 \times 10^{-3}\text{ mm}\)

\(\:\:\:\:\:\:\:7.78 \times 10^{-3}\text{ mm}\)

PREFIK

 

\begin{array}{cccc} \color{blue}\text{Prefik} && \color{blue}\text{Simbol} &&\color{blue} \text{Faktor dari 10}\\\\ \text{peta} && \text{P} && 10^{15}\\\\ \text{tera} && \text{T} && 10^{12}\\\\ \text{giga} && \text{G} && 10^{9}\\\\ \text{mega} && \text{M} && 10^{6}\\\\ \text{kilo} && \text{k} && 10^{3}\\\\ \text{hekto} && \text{h} && 10^{2}\\\\ \text{deka} && \text{da} && 10^{1}\\\\ \text{desi} && \text{d} && 10^{-1}\\\\ \text{centi} && \text{c} && 10^{-2}\\\\ \text{milli} && \text{m} && 10^{-3}\\\\ \text{mikro} && \mu && 10^{-6}\\\\ \text{nano} && \text{n} && 10^{-9}\\\\ \text{piko} && \text{p} && 10^{-12} \end{array}

 

Contoh:

\(2.5 \text{ nm} =\dotso \text{ km}\)

\(\text{nano} = 10^{-9}\)

\(\text{kilo} = 10^3\)

Kurangkan pangkat 10 dari nano dengan pangkat 10 dari kilo

\(2.5 \text{ nm} = 2.5 \times 10^{-9-3}\text{ km} = 2.5\times 10^{-12}\text{ km}\)

KONVERSI

 

1 kg = 1000 gram

1 kg = 10 ons

1 kg = 2 pon

1 ons = 100 gram

1 ton = 1000 kg

1 liter = 1 dm3 = 0.001 m3

1 liter = 1000 cm3 = 1000 cc

1 ml = 1 cm3 = 0.001 liter

1 menit = 60 detik

1 jam = 60 menit = 3600 detik

1 hari = 24 jam
