Question

MEDAL AND FAN

Part A: Use the properties of exponents to explain why 18 to the power of 1/5 is called the fifth root of 18. (5 points)

Part B: The length of a rectangle is 2 units and its width is (square root symbol) 2 unit. Is the area of the rectangle rational or irrational? Justify your answer. (5 points)

Answer 1

I'm not really sure but 18^1 = 18. And typically the roots of something are in the denominator, so (18^1)/5 is 18/5 and 5 would be the 5th of 18 possible roots?
Not sure but that's my guess for question A

Answer 2

for b the answer is going to be easy to see it is irrational because the formula for a rectangle is length times width. this would be \[2\sqrt{2}\] and a sqrt root in your answer that cannot be reduced is irrational

Answer 3

He got b

Answer 4

You copied A from another post lol.

Answer 5

hey but I edited and its right! haha

Answer 6

idk I don't think that's right.

Answer 7
