i)1.224 \times 10^{7}  ii) 1.9558 \times 10^{-1}

விளக்கம்:

\text { (i) }\left(1.02 \times 10^{10}\right) \times\left(1.20 \times 10^{-3}\right)

\left(1.02 \times 10^{10}\right) \times\left(1.20 \times 10^{-3}\right)

=(1.02 \times 1.20) \times\left(10^{10} \times 10^{-3}\right)

=1.224 \times 10^{10-3}

=1.224 \times 10^{7}

\left(\text { ii) }\left(8.41 \times 10^{4}\right) \div\left(4.3 \times 10^{5}\right)\right.

\left(8.41 \times 10^{4}\right) \div\left(4.3 \times 10^{5}\right)

=\frac{8.41 \times 10^{4}}{4.3 \times 10^{5}}

=\frac{841 \times 10^{2}}{43 \times 10^{4}}

=19.558 \times 10^{-2}

=1.9558 \times 10^{-2+1}

=1.9558 \times 10^{-1}
