(x+1)(x+2)
= x^2 + 3x + 2
but x = log<sub> 5 </sub>10
x+1 = log<sub> 5 </sub>10 + log<sub> 5 </sub>5
= log<sub> 5 </sub>50
x+2 = log<sub> 5 </sub>10 + 2log<sub> 5 </sub>5
= log<sub> 5 </sub>10 + log<sub> 5 </sub>25
= log<sub> 5 </sub>250
(x+1)(x+2) = (log<sub> 5 </sub> 50)(log<sub> 5 </sub> 250)
= appr 8.338865
= x^2 + 3x + 2
but x = log<sub> 5 </sub>10
x+1 = log<sub> 5 </sub>10 + log<sub> 5 </sub>5
= log<sub> 5 </sub>50
x+2 = log<sub> 5 </sub>10 + 2log<sub> 5 </sub>5
= log<sub> 5 </sub>10 + log<sub> 5 </sub>25
= log<sub> 5 </sub>250
(x+1)(x+2) = (log<sub> 5 </sub> 50)(log<sub> 5 </sub> 250)
= appr 8.338865
