Answer:

 \frac{1}{4}   <  log_{10}(2)  <   \frac{1}{3}

Step-by-step explanation:

think,

log10 2= a

 {10}^{a}  = 2

lcm of 3 and 4 is 12.

{10}^{12a}  =  {2}^{12}  = 4098

we know that,

1000 < 4098 < 10000 \\  =  {10}^{3}  <  {10}^{12a}   <   {10}^{4}  \\  = 3 < 12a < 4 \\  =  \frac{1}{4}  < a <  \frac{1}{3}  \\  =  \frac{1}{4}  <  log_{10}(2)  <  \frac{1}{3}
