Question 671781: i would just like for someone to check my answers if they could, please.
it says, " use your calculator to solve for x. round your answers to the nearest thousandth."
10^2.3=x i got .362
e^x=9 i got 2.197
10^x=15 i got 1.176
e^-1.5=x i got .176

Hi,

use your calculator to solve for x. round your answers to the nearest thousandth."

 x = 10^2.3   ||careful, always 'try' to visualize or 'estimate' answer 10%5E2+=+100

 10^2.3 = 199.526

ln 9 = 2.197,  Yes.  Good work

log(15) = 1.176, Yes.  Good work 

 e^(-1.5) = 1/e^1.5 = 1/4.482 =  .223    || 1/e^1 = 1/(2.718) = .368  , for ex
