math -logarithm

Write the equations in logarithmic form.
(a)
729 = 93(9 to the 3rd power)

(b)
25 = 1/5 −2( 1/5 to the -2 power)


a = bc ( c squared)

  1. 729=9³
    log9729 = 3

    25 = (1/5)-2
    log(1/5)25 = -2

    for a=bc²
    rearrange to
    (a/b) = c²
    and proceed similar to above.
