Example Question #892 : Concepts

Solve for

Possible Answers:

Correct answer:

Explanation:

By using order of operations we must first multiply by using the distributive property

This gives us:  

Next we must combine like terms:

Rewrite the equation after combining like terms: 

Add a positive 2 to both sides of the equation. 

Again combine like terms and rewrite equation 

Divide by 4 on both sides of the equation 

 

Example Question #91 : How To Find The Solution To An Equation

Simplify:

Possible Answers:

Correct answer:

Explanation:

When we have an exponent raised to an exponent, our rule is to multiply the exponent by the exponent.  Lets look at an easier problem to show this rule.

In this problem it is saying two squared, times two squared correct? (Yes)

So what is 2 squared? (4), what is 2 squared again? (4).

So this problem is saying  which is . This is one way we can do the equation. Another is a rule that was mentioned before. When we have an exponent raised by an exponent *only in these cases* we can multiply the exponents by each other. 

So in our easier example the exponent  times the other exponent .

Looks like this 

Or the same thing as saying

. Either way we get the same answer!

Returning back to the original problem. We have the exponent 2 raised to the exponent 8. We can multiply them by each other in this case. 

So as the question asks us to simplify we just need to put
