    indice thing 2

    given that, in standard form:
    3^236 is approximately equal to 4 x 10^112
    3^-376 is approximately equal to 4 x 10^-180
    find approximations, also in standard form, for
    a. 3^376
    b. 3^612
    c. (sqrt3)^236
    d. (3^-376)^(5/2)

    i dont know how to apply the given info to the question! i dont even know where to start. this must be simple when its understood, so i just need a helpful hint

    Ok with a) reverse 4 x 10^-180 into positive.

    b) whats 376 plus 236= 612 and then you just add the powers.

    c) if you can find the sqrt of 4 x 10^112 then you have your answer.

    d) (5/2) also means: 5 means to the power of and the 2 means sqrt of. so add the power of 5 and sqrt the answer same as c).

    Hope that helps.
