How to solve an expression with variables in the exponents?

Mathematics
1 answer:
gtnhenbr [62]3 years ago
8 0

Answer:

  use logarithms

Step-by-step explanation:

Taking the logarithm of an expression with a variable in the exponent makes the exponent become a coefficient of the logarithm of the base.

__

You will note that this approach works well enough for ...

  a^(x+3) = b^(x-6) . . . . . . . . . . . variables in the exponents

  (x+3)log(a) = (x-6)log(b) . . . . . a linear equation after taking logs

but doesn't do anything to help you solve ...

  x +3 = b^(x -6)

There is no algebraic way to solve equations that are a mix of polynomial and exponential functions.

__

Some functions have been defined to help in certain situations. For example, the "product log" function (or its inverse) can be used to solve a certain class of equations with variables in the exponent. However, these functions and their use are not normally studied in algebra courses.

In any event, I find a graphing calculator to be an extremely useful tool for solving exponential equations.

Sam bought a soda and a bag of chips for $3. If the soda cost $1.75, how much was the bag of chips?
Anarel [89]

Answer:

1.25

Step-by-step explanation:

The bag of chips is worth the same as the entire purchase minus the soda.

Therefore the chips are worth 3 - 1.75 = 1.25
