Question 752544
9216 = 2^10 * 3^2

log(2,(9216) = log(2,(2^10 * 3^2)

log (2,(2^10 * 3^2) = log(2,2^10) + log(2,3^2)

log(2,2^10) + log(2,3^2) = 10 * log(2,2) + 2 * log(2,3)

10 * log(2,2) + 2 * log(2,3) = 10 * 1 + 2 * 1.5850 = 13.17.

you can use your calculator to confirm.

log(2,9216) = log(10,9216) / log(10,2) = LOG(9216) / LOG(2) = 13.l69925

that's pretty close (13.17 / 13.169925 = 1.000005695.
