When the radicand is a negative
The dice only has 6 sides so if you need to roll a 2 or less that only leaves the number one. So it would be 2/6
Your answer is 22 x 18 x 9 = 3,564
Hello from MrBillDoesMath!
Answer:
Choice D, x = +\ sqrt(121)
Discussion:
x^2 = 121 => take square roots of both sides
x = +\- sqrt(121) => as sqrt(121) = +\- 11
x = +\- 11
The closest answer is D as it includes both values of x, unlike choices A and B which include a single value of the square root
Thank you,
MrB
