Step-by-step explanation:

Question 1.

Given:

We need to Simplify given expression we get;

Solution:

Now we know that;

By Using Law of Indices which states;

So we get:

Now Again By Law of Indices we get;

So we get:

Hence Simplified expression is  .

Question 2.

Given:

We need to solve for 'y'.

Solution:

To find 'y' we need to first make the base same.

Now we know that;

So we can say that:

Now Applying Distributive property we get;

Now we can say that;

When an expression has equal bases then their exponent are said to equal too.

from above we get;

Combing like terms we get;

Dividing both side by 2 we get;

Hence The Value of y is 5.25.
