Write each expression
using positive
exponents, then
evaluate.

The answer is

Step-by-step explanation:

* Lets explain how to solve the problem

- Any number to power of zero = 1 (except 0)

- Ex:  and  

- If the power of a number is negative we can change it to positive

 if we reciprocal the number

- Ex:  and  

* Lets solve the problem

- We want to write each expression  using positive  exponents,

 and evaluate

#

∵ Zero is not a positive exponent

- Change to 1 because 1 has positive exponent 1

∴

#

- We can written it as

∴

#

- Change the negative exponent by reciprocal 9

∴

∴

- Lets evaluate

∵ 5³ = 125 and 3³ = 27

∴ 5³ × 3³ = 3375

∴

∴

∴ The answer is

step-by-step explanation:

just plug in each number for x and see which ones work and don't

good job you smart son of a gun you are smarter that einstein. 7
