2=ab^2 1/2=ab^0

Anonymous has a correct procedure; another one is:

Since  b^0 = 1, the equation:  ½ = a·b^0  becomes  ½ = a.

Replace this value for a into the first equation:  2 = a·b²  gives you 2 = ½·b².

Multiply both sides by  2:  4  =  b²   --->  b = 2  or  b = -2.

 No I will not solve it 😈

Please!!

I don't know how 😈

You divide them. Subtract the powers. Get rid of the a.
