Solution:Here we are given that and we need to find the value of x
So firstly we can simplify this equation by opening the bracket and analyse the power of each variable a and b and we must also know that when we have two terms in the power then they are multiplied. For example: If we have then we can write it as
So we can write
Now we have got the left and the right hand side in the simplified form and we need to find the value of x
So we know that if we are given then we can say that x=y by equating the power of the same variable on both sides.
Similarly equating the power of aa on both the sides in the equation (1) we get that
Upon solving it we get
Hence we get that x=1
Now again equating the power of bb on both the sides we get
Hence we get that the value of x=1
Hence we can say that option 1 is correct.
