Question

±√121 what is the answer

Answer 1

Answer:

±√121 = ±11 (11, -11)

Step-by-step explanation:

1.First, find two equal numbers multiplied by each other to get 121:

This will be 11×11, so the answer for the square root is +11 or -11.

2. Or you can find the square root of a number using this method:

• draw a line splitting two sides from each other.

• then, write the number inside the square root on the left side of the line.

• after that, on the right side, write a number that can be divided by 121 ( it should be a whole number and a prime number).
• write the answer to the division on the left side of the line.
• next, rewrite the two steps above by writing a number that can be divided by the answer of the division.
• stop writing the number when you get to number one on the left and right sides.
• finally, match every two equal number together to make it on the number and multiply them together to get the answer for the square root.
• you can understand it more from the picture below, I also did another example for this method.
