Calculate or simplify the expression \( 5*10^(-1)+3*10^(-3)+7*10^(-4) \).
Calculate the value by following steps:
- step0: Calculate:
\(5\times 10^{-1}+3\times 10^{-3}+7\times 10^{-4}\)
- step1: Add the numbers:
\(\frac{503}{1000}+7\times 10^{-4}\)
- step2: Rewrite the expression:
\(\frac{503}{1000}+\frac{7}{10000}\)
- step3: Reduce fractions to a common denominator:
\(\frac{503\times 10}{1000\times 10}+\frac{7}{10000}\)
- step4: Calculate:
\(\frac{5030}{10000}+\frac{7}{10000}\)
- step5: Transform the expression:
\(\frac{5030+7}{10000}\)
- step6: Add the numbers:
\(\frac{5037}{10000}\)
