Question

| 12,300,000,000 convert the following number to scientific notation​

Answer 1

scientific notation means, we move the decimal dot over so that we leave only 1 digit to the left of the dot.

hmmm let's see

$\bf 12300000000\implies \stackrel{\leftarrow \textit{10 slots over}}{12300000000}.0\implies 1.2300000000.0\times 10^{10} \\\\[-0.35em] ~\dotfill\\\\ ~\hfill 1.23\times 10^{10}~\hfill$

Answer 2

1.23 times 10 to the 10th power
