if 2w -1 =2 what is the value of w(expontent2) -1

Answer 1

2w - 1 = 2 means that 2w = 2 + 1 = 3, that is w = 3/2

w(exponent2) - 1 = w^2 - 1 = (3/2)^2 - 1 = 9/4 - 1 = (9-4)/4 = 5/4

Answer 2

you have to split the 2 from the w to see what equals to w. The way to limit a number with the letter is through division. Remember, whatever you're doing on one side, you must do the other side.
