Answer:
Sadie's error is " she made error in step 2 
where 
"
Because she made error in splitting the powers to simplify the square root
<h3>Therefore the correct answer for Sadie's expression is
where </h3>
Step-by-step explanation:
Given that " Sadie simplified the expression StartRoot 54 a Superscript 7 b cubed EndRoot, where a greater-than-or-equal-to 0, "
It can be written as 
where
The given expression is where
To find Sadie's error and explain the correct answer :
Sadie's steps are

Answer:
f) 
e) 
d) 
c) 
b) 
a) 
Step-by-step explanation:
- m∠5 ≅ m∠4; Angle Correspondence Theorem
- m∠5 ≅ m∠1; Alternate Interior Angles Theorem
- m∠6 ≅ m∠2; Alternate Exterior Angles Theorem
- 180° = m∠2 + m∠1; Definition of Linear Pair [Supplementary Angles]
- 180° = m∠5 + m∠3; Definition of Linear Pair [Supplementary Angles]
I am joyous to assist you anytime.
He pays $135 for 3 years. So that’s $45/year. Considering 900 is your 100%, how many percents are represented by $45 in 900?
1)
You can see that 900 = 9x100.
So you can divide 900 by 9 to get 100.
That means you can also divide 45 by 9 (it’s proportional)
You have 45 for 900, you divide by 9 so you get 5 for 100 -> 5%
Or 2)

It’s a cross-multiplication :
(45 x 100)/900 = 5%
So the interest rate is 5%.
