Tell what the output value is for the function machine for the given values.

log 16.9=1.23
log2^152=9
log2^1=0
log0.046=1.34

thank you

  • algebra/please can you ck my answers -

    log base ten of 16.9 = 1.23

    log2 (512 not 152) = 9
    because
    base^log x = x
    2^9 = 512

    log 1 = 0 for any base at all
    because
    any base^0 = 1

    log base 10 = log10(.046) = -1.34 that is NEGATIVE 1.34
