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 $log_{a}(a^b)=b$

X - 3= -21 <br>This is so confusing:(

Aneli [31]

Answer:

$\huge\boxed{x=-18}$

Step-by-step explanation:

In order to solve this, we are trying to find the value of $x$ . Basically, $x$ is a placeholder for a number that is unknown. Some number minus 3 is equal to 21.

Our goal is to find $x$ . To do this we want to isolate $x$ on one side of the equation

$x-3=-21$

Let's add 3 to both sides.

$x-3 + 3 = -21+3\\\\-3 + 3 = 0\\\\x = -21+3\\\\x=-18$

Hope this helped!
