i)1.505 \times 10^{8}  ii)1.5522 \times 10^{17}

விளக்கம்:

\text { (i) }\left(2.75 \times 10^{7}\right)+\left(1.23 \times 10^{8}\right)

\left(2.75 \times 10^{7}\right)+\left(1.23 \times 10^{8}\right)

=10^{7}[2.75+12.3]

=10^{7}[15.05]

=15.05 \times 10^{7}

=1.505 \times 10^{7+1}

=1.505 \times 10^{8}

\text { (ii) }\left(1.598 \times 10^{17}\right)-\left(4.58 \times 10^{15}\right)

\left(1.598 \times 10^{17}\right)-\left(4.58 \times 10^{15}\right)

=10^{15}[1.598 \times 100-4.58]

=10^{15}[159.8-4.58]

=155.22 \times 10^{15}

=1.5522 \times 10^{15+2}

= 1.5522 \times 10^{17}
