Question

if x^2 = 100
what is x?

Answer 1

\[\sqrt{100}=x\]

Answer 2

that's the most accurate way to get the answer. since 100 is a perfect square, then the answer would be 10. and 10 can be squared to 100.

Answer 3

Use the square root property to solve the equation. The equation has real number solutions.

Answer 4

what times itself multiplies to 100

Answer 5

\[\pm10\] meaning -10 and 10 could be x.

Answer 6

@mrmudd183
You have to remember that the square root will result in \(\pm\) values

Answer 7

\(x^2=100\)

\(x^2-100=0\)

\((x-10)(x+10)=0\)

so \(x=10\) or \(x=-10\)

Answer 8

ok, thank you TSO. i kind of forgot about that. it's kind of been a while. but i'm trying my best to help, but math isn't my strongest subject

Answer 9

3 ways: sqrt100, what times it self = 100 (mental maths), or zarkon's way
