Simplify.

(-3 ab^3 ) ^4

The simplified expression is:

Step-by-step explanation:

To simplify the expression given we, need to open the brackets, and if there is power term. then we need to find the individual power of each variable.

Now the expression that is given to us is:

Here we will simplify it, as follows:

as we know that when n is even we have:

Now, the expression is simplified as:

So this is the required simplified form.

step-by-step explanation:

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
