    Calculating percentage of exponents.

    Trying to figure out some astronomy. Please let me know if I am doing this correctly.

    I want to find 95% of 1.98 x 10^30.

    I divided 1.98 x 10^30 by 100 to get 1.98 x 10^28. Then multiplied 1.98 x 10^28 by 95 to get 1.88 x 10^30. So I have 1.88 x 10^30 as 95% of 1.98 x 10^30. Is that the way you do it? thanks.

    I mean usually people do 95% =.95...

    .95 \times (1.98 \times 10^{30}).
