Answer:
Option A
Step-by-step explanation:
Solution 1
[tex]\sqrt[5]{\sqrt[]{(x+3)^{20} } }[/tex]=[tex]\sqrt{(x+3)^20 /5}[/tex]= [tex]\sqrt{(x+3)^4}[/tex]=(x+3)⁴/²=(x+3)²
Solution 2
[tex]\sqrt[5]{\sqrt[]{(x+3)^{20} } }=[/tex][tex]\sqrt[5]{(x+3)^20/2}[/tex]= [tex]\sqrt[5]{(x+3)^10}[/tex]= (x+3)¹⁰/⁵= (x+3)²
As you can see the mistake was at first step, where power should have been put as 20/2 instead of 2/20 (according to solution 2 above)
But it wasn't Edward's solution, he went by solution 1 above
There is no connection between Edward's solution and answer options
But best fit is Option A
