Can someone explain this problem to me? it's confusing.

The answer is ±8

Step-by-step explanation

Remember that the answer to a square root is the number that multiplied by himself is equal to the number given> in this case (64=8·8)

When you have a square root(sqrt) there are two posibble solutions:

A positive one and a negative one

in this case 8·8=64 and (-8)·(-8)=64 so both answers are posible

+√64=8

-√64=-8

±√64=±8

11

step-by-step explanation:

32.50-7.50=25

225/25=11

you have to wait a while to reward brainliest if only one person answers. if 2 people answer there should be a "mark brainliest" on their question.
