the direction reads

given that log 2 = 0.3010 and log 3 = 0.4771, state an equation you can use to find approximations of the logarithms of each of the following numbers without using a table. Then find the approximations.

a. 4
b. 8
c. 1/2



can someone please help me? :eek: :( :confused: :confused: :)

Given log(2)=0.3010, you could try:

log(2^{t})=tlog(2)

Note the powers the powers of 2. 2^2=4, 2^3=8, etc.

U don't even need to know log 3 = 0.4771...
