i)4.32 \times 10^{29}  ii)6.25 \times 10^{30}

விளக்குக:

i) (300000)^{3} \times(2000)^{4}

(300000)^{3} \times(2000)^{4}=\left(3.0 \times 10^{5}\right)^{3} \times\left(2.0 \times 10^{3}\right)^{4}

= 3.0^{3} \times\left(10^{5}\right)^{3} \times 16.0 \times 10^{12}

=27.0 \times 10^{15} \times 16.0 \times 10^{12}\times\left(1.6 \times 10^{1}\right) * \left(10^{12}\right)

=2.7 \times 1.6 \times 10^{1} \times 10^{15} \times 10^{1} \times10^{12}

=4.32 \times 10^{1+15+1+12}

=4.32 \times 10^{29}

ii)(50000000)^{4}

=\left(5.0 \times 10^{7}\right)^{4}

=(5.0)^{4} \times\left(10^{7}\right)^{4}

=625.0 \times 10^{28}

=6.25 \times 10^{2} \times 10^{28}

=6.25 \times 10^{30}
