12 + x to the power of 4 - 6 when x = 8

iren [92.7K]

value of $12+x^4-6$ at x=8 is $5002$ .

<u>Step-by-step explanation:</u>

here we need to evaluate 12 + x to the power of 4 - 6 when x = 8 or , $12+x^4-6$ where x=8 . Let's find out:

⇒ $12+x^4-6$

Putting x =8 :

⇒ $12+8^4-6$

Splitting 8 to power 4 into 8 to power 2 ( 2 times )

⇒ $12+8^2(8^2)-6$

⇒ $12+64(64)-6$

⇒ $12+4096-6$

⇒ $4096+6$

⇒ $5002$

Therefore , value of $12+x^4-6$ at x=8 is $5002$ .

You have just isolated a new radioactive element. If you can determine its half-life, you will win the Nobel Prize in physics. Y

Staals half
1 gram left
0.3 grams left
half lives are normally written in years
it goes likt this

$A=P( \frac{1}{2})^ \frac{t}{h}$
A=final amount
P=initila amount
t=time elapsed
h=time half life is (same units as time)

let's use days as the units of time

we are given
initial amount=1gram
final amount=0.3gram
time=4 days

so
$0.3=1( \frac{1}{2})^ \frac{4}{h}$
solve for h
$0.3=( \frac{1}{2})^ \frac{4}{h}$
take the ln of both sides
$ln(0.3)=ln( \frac{1}{2})^ \frac{4}{h}$
$ln(0.3)=\frac{4}{h}ln( \frac{1}{2})$
times both sides by h
$hln(0.3)=4ln( \frac{1}{2})$
divide both sides by ln(0.3)
$h= \frac{4ln( \frac{1}{2}) }{ln(0.3)}$
use calculator
h=2.30287
3 sig figs
h=2.303 days
