i)1.44 \times 10^{28}  ii) 8.0 \times 10^{-60}

விளக்குக:

\text { (i) }(300000)^{2} \times(20000)^{4}

=\left(3.0 \times 10^{5}\right)^{2} \times\left(2.0 \times 10^{4}\right)^{4}

=(3.0)^{2} \times\left(10^{5}\right)^{2} \times(2.0)^{4} \times\left(10^{4}\right)^{4}

=(9.0) \times(2.0)^{4} \times 10^{10} \times 10^{16}

=(9.0) \times(1) \times 10^{10+16}

=144 \times 10^{26}

=1.44 \times 10^{28}

\text { (ii) }(0.000001)^{11} \div(0.005)^{3}

=\left(1.0 \times 10^{-6}\right)^{11} \times\left(5 \times 10^{-3}\right)^{3}

=\frac{(1.0)^{11} \times\left(10^{-6}\right)^{11}}{5^{3} \times 10^{-9}}

=\frac{1}{125}* 10^{-66+9}

=0.008 \times 10^{-57}

=8.0 \times 10^{-57-3}

=8.0 \times 10^{-60}
