Question

If x + log10(1 + 2x) = xlog10 5 + log10 6 then x is equal to (a) 2, –3 (b) 2 only (c) 1 (d) 3

Answer 1

I think your question is incorrect.

your question should be


If x + log10(1 + 2) = log10 5 + log10 6 then x is equal to (a) 2, –3 (b) 2 only (c) 1 (d) 3 ?

The symbol "i" is only allowed in complex arithmetic, for example:
     (3/5+7i)+(0.3-7.002i) 
     (5+77i)-(19/4-8i) 
     (240-22i)*(247/7+2.222i) 
     (33/5+99i)/(33/5-88i) 

Unauthorized use of the imaginary unit "i" or syntax error in complex arithmetic expression
