Dane sa liczby a=2,3x10do19 oraz b=3x10do-8 zapisz w notacji wykladniczej liczbe ab kwadrat Prosze pilne!
a = 2,3 x 10^19
b = 3 x 10^(-8)
ab^2 = a * b^2 a * b * b = 2,3 x 10^19 x 3 x 10^(-8) * 3 x 10^(-8) = 2,3 x 3 x 3 x 10^(19 + (-8) + (-8)) = 20,7 x 10^(19 - 16) = 20,7 * 10^3 = 2,07 * 10 ^ 10^3 = 2,07 * 10^4
