Exponents are found by using their inverse: logarithms.

By definition:

a = bx

rearranges to: x = logb(a)

Most scientific calculators support this function.

What is biased exponent?

A biased exponent is an exponent that is, in layman's terms, set aside when being used in high valued numbers, and basically just stored until the value of the number in the biased exponent needs to be used to solve an equation.


How do you solve when you have a negative exponent?

A negative exponent is the same as 1/(the positive exponent). For example, 2^3 is (2*2*2) = 8. 2^(-3) is 1/(2*2*2) = 1/8. So, just calculate the positive exponent version, and put it under 1.


How do you write a decimal using a negative exponent?

When you have a negative exponent (for example 3^-3) you could make the recipricol of the number. So, this would be 1/3^3. Then all that you would have to do is solve for the exponent ( so in this case the answer would be 1/27)


How do you solve algebraic expressions with missing exponents?

You cannot because an exponent cannot be solved: only an equation or inequality can be solved. In any case, the answer will depend on the nature of the equation and which exponent is missing. Without that information there cannot be any sensible answer.


How do you solve 16y exponent 3 20y exponent 4?

16y3 / 20y4 = 16/20 * y3/y4 = 4/5 * y3-4 = 4/5 * y-1 or 4/5y


How do you solve an exponent if it's by the power of zero?

Any exponent to the power of zero is simply 1, with the exception of zero itself! Zero to the power of zero has no definitive answer, though it may sometimes be taken as equal to one.


How do you solve for a negative exponent?

That depends what you want to solve. In many cases, it helps to remember the basic definition: for example, x ^ (-3) = 1 / x ^ 3. (Using the symbol "^" for powers.)
