Question

Hi! Can someone help me with this? Properties and Logarithmic Functions.

Answer 1

$2\log_{10}x + \log_{10}5 = \log_{10}x^2 + \log_{10}5 = \log_{10}5x^2$

So the answer is $\log_{10}5x^2$

------------------

I used the log rules

y*log(x) = log(x^y)

log(x) + log(y) = log(x*y)

these rules apply to any log base (not just base 10).
