Answer:
x^16
Step-by-step explanation:
We know that a^b * a^c = a^ (b+c)
x ^7 * x^9
x^(7+9)
x^16
The solution to the linear equation:
8h + 5 - 3h = 8h - 4
is h = 3.
<h3>
How to solve the linear equation?</h3>
Here we have the linear equation:
8h + 5 - 3h = 8h - 4
To solve it, we need to move all the terms with h to the left side of the equation and the terms without x to the right side:
8h - 3h -8h = -4 - 5
-3h = -9
Now we can divide both sides by -3 to get:
h = -9/3 = 3
We conclude that the solution to the linear equation is h = 3.
