Given that 2^x = 7, find the value of 4^x-1.

Helga [31]

$4=2^2\\\\4^x=(2^2)^x=(2^x)^2=7^2=49\\\\4^x-1=49-1=48$

$If\ is\ 4^{x-1},\ then\\\\4^{x-1}=\dfrac{4^x}{4}=\dfrac{49}{4}=12\frac{1}{4}$

$Used:\\\dfrac{a^n}{a^m}=a^{n-m}$

The population of Portland Oregon has recently grown to more than 500,000. What is the order of magnitude for the number of peop

miss Akunina [59]

Answer:

Order is 6

Step-by-step explanation:

The population of Portland Oregon has recently grown to more than 500,000.

The order of magnitude for the number of people in Portland means the power of 10. It means that we need to write 500,000 in form of 10 to the power. So,

$P=500,000$

It contains 6 zeroes. It means,

$P=5\times 10^6$

So, the order of magnitude for the number of people in Portland is 6.

Solve xy -5= k for x

Virty [35]

Hey there!

To solve, let's first add 5 to both sides.

xy=k+5

Now we divide both sides by y.

x= $\frac{k+5}{y}$

I hope this helps!
