4. rewrite each number in exponential notation using 3 as the base.
a. 9 = 3 x 3 = 32
b. 27 = 3 x 3x3 = 33
c. 81 = 3x3x3x3 = 34
d. 243 = 3x3x3x3x3 = 35
i need asap

Step-by-step explanation:

It is important to remember the that Exponential notation is in the form:

Where:

Therefore, given the numbers , you need to descompose them into their prime factors and then you must write them in exponential notation using 3 as the base.

Then:

what? ?

what type of question is thiss

step-by-step explanation:

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
