Find k and help with the equation!

=======================================================

Work Shown:

The result is in the form with k = 6+10x

------------------------

Explanation:

First we need to get everything as an exponential expression with a base 2.

We rewrite 64 as and 4 as in the second step.

In the third step, I used the rule which says to multiply the exponents together. That's how I went from to . Then the 2*5x in the exponent becomes 10x.

To wrap things up, I used the rule which says to add the exponents when we multiply stuff of the same base together.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
