Wondering the answers to these:

Find the value of each of the following. Leave your answers as fractions where appropriate.

[I did these myself but need to answer-check]

a) log[base4](1/8)

b) 10^(-10log3)

c) 2log[base3](9)

d) log[base3](3)^(2x)

ans:

a) -3/2

b)(1/3)^10

c) 4

d)3x

These may be wrong, please give me feedback, thx

  • math -

    a) corrrect
    b) 10^(-10log3)
    = 10^(log3^-10
    = 3^-10 ...... using the property a^logak = k

  • math -

    c) correct

    d) log3 3^(2x)
    = 2x log3 3
    = 2x(1)
    = 2x
