I need to calculate X<br><br> 2^x=200<br><br> Solve for x

antoniya [11.8K]

Remember
$log(a^z)=zlog(a)$
so

notice that 200=2*2*2*5*5, so x cannot be a whole number

take the log base 10 of both sides

$log_{10}(2^x)=log{10}(200)$
$xlog_{10}(2)=log{10}(200)$
divide both sides by $log_{10}(2)$
$x= \frac{log_{10}(200)}{log_{10}(2)}$

if we used $log_{2}$ instead of $log_{10}$ we would get
$x= log_{2}(200)$ because $log_{a}(a^b)=b$

What is the unit rate for 5 pounds of lunch meat for $42.50?A. $5.31 per poundB. $6.50 per poundC. $7.25 per poundD. $8.50 per p

KengaRu [80]

Hey there! I'm happy to help!

We want to find how much money the lunch meat costs for one pound. We see that it costs $42.50 for 5 pounds, so we simply divide by 5 to see how much it costs for 1 pound.

42.5/5=8.5

Therefore, the answer is D. $8.50 per pound.

Have a wonderful day! :D
