Answer:
Step-by-step explanation:
Given that,
An equation : 274.6 = 2.746 x 10n
To find,
The value of n.
Solution,
We have, 274.6 = 2.746 x 10n
Dividing both sides by 2.746 .
![\dfrac{274.6 }{2.746 }=\dfrac{10n\times 2.746 }{2.746 }\\\\10n =100](https://tex.z-dn.net/?f=%5Cdfrac%7B274.6%20%7D%7B2.746%20%7D%3D%5Cdfrac%7B10n%5Ctimes%202.746%20%7D%7B2.746%20%7D%5C%5C%5C%5C10n%20%3D100)
Now dividing both sides by 10.
n = 100/10
n = 10
So, the value of n is 10.
I’m not sure what the amount would be but it would take her 32 months
First let's review how to expand this!
(ax+b)^2=a^2*x^2+2abx+a^2
In this case
(2x^2+1/2)^2=2^2*x^2+2*1/2*2x+(1/2)^2
=4x^2+2x+1/4
Done!
