How do you solve #36w^2=121#?

Answer 1

Eli Assouline

#w=+-11/6#

#"Isolate "w^2" by dividing both sides by 36"#

#(cancel(36) w^2)/cancel(36)=121/36#

#rArrw^2=121/36#

Take the #color(blue)"square root" # of both sides.

#sqrt(w^2)=+-sqrt(121/36)=+-sqrt121/sqrt36#

#rArrw=+-11/6#

To solve 36w^2 = 121, you first divide both sides by 36 to isolate w^2. Then, you take the square root of both sides to solve for w.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
