    Remember a^-b = 1/(a^b)

    (1/3^2)+(1/9^2) (1/9)+(1/81) (9+1)/81 10/81

    I'm trying to say when you have a a number raised to a negative exponent its 1 divided by the number to the positive exponent. So like the first one 3^-2 is the same as 1/(3^2)

    asma: toshiko wants to determine what type of freproduction a particualr single -celled organism undergroes .she conducts an experiment in which she anaylazes the chromosomes of the organism,she allows time for the the organisms to reproduce ,and then she anyalazes the chromoses of the duaghter cells.she discovers that all of the organisms offspring are gentically identical to the original orgaisinim asma: 1) identify the dependent (responding) varibale in toshikos experimnent.

    looks like biology lol id say they reproduce asexually if its biology if math then the word that comes to mind is exponentially?

    So as I said the dependent variable should be the population

    And id say it reproduces asexually meaning it splits apart (multiplies)
