Exponential equations generally have the unknown variable as the power. The
following are examples of exponential equations:
You should already be familiar with exponential notation. Solving exponential
equations is simple, if we remember how to apply the laws of exponentials.

Equality for Exponential Functions
If
is a positive number such
that
, (except when
) then:
if and only if:
(If
, then
and
can differ)
This means that if we can write all terms in an equation with the same base, we
can solve the exponential equations by equating the indices. For example takethe equation
. This can be written as:
Since the bases are equal (to 3), we know that the exponents must also be equal.
Therefore we can write:
This gives:
Method: solving exponential equations
Try to write all terms with the same base.
Equate the exponents of the bases of the left and right hand side of the equation.
Solve the equation obtained in the previous step.

Write the following with the same
base. The base is the first in the list. For example, in the list 2, 4, 8, thebase is two and we can write 4 as

Solve for
:
All terms are written with the same base.
Since both sides are equal, the answer is correct.
In economics, a perfect market refers to a theoretical construct where all participants have perfect information, goods are homogenous, there are no barriers to entry or exit, and prices are determined solely by supply and demand. It's an idealized model used for analysis,

Quantity demanded refers to the specific amount of a good or service that consumers are willing and able to purchase at a give price and within a specific time period. Demand, on the other hand, is a broader concept that encompasses the entire relationship between price and quantity demanded

What do you think is more important to focus on when considering inequality ?
sir...I just want to ask one question... Define the term contract curve? if you are free please help me to find this answer 🙏
Asui
it is a curve that we get after connecting the pareto optimal combinations of two consumers after their mutually beneficial trade offs

thank you so much 👍 sir

In economics, the contract curve refers to the set of points in an Edgeworth box diagram where both parties involved in a trade cannot be made better off without making one of them worse off. It represents the Pareto efficient allocations of goods between two individuals or entities, where neither p
