what is log250 to the base 10

Question

log₁₀250=?

Answer 1

I assume by "what is" you mean "simplify":

 

log(250)                      [log = log base 10]

= log(5²·10)

= log(5²) + log(10)      [Log property:  log(ab) = log(a) + log(b)]

= 2 log(5) + 1           [Log properties: log(a^b) = b log(a)   and  log₁₀(10)=1]
