Question

U^2=64 solve using square root property

Answer 1

u = ±8

Explanation:

Given: u^2 = 64.

Solve for u by taking the square root of both sides AND putting the ' ± ' symbol in front of the right side:

√u² = ±√64, or u = ±8

Answer 2

`u=8,\ u=-8`

Explanation:

u² = 64

`u\² = 64\\\\` <== you take the square root of both sides

`√(u\²) = \±√(64) \\\\`

`u= \±8\\\\` <== (u = plus or minus 8)

`u=8,\ u=-8\\`

Hope this helps!
