When you divide exponents, you just subtract them. the answer to this equation is a^2 (a squared). This is because 8-6 = 2. Conversely, if you were multiplying two terms with exponents you would add the exponents together. For example: a^3 * a^2 = a^5, because 3 + 2 = 5

<h3>What is a system of equations?</h3>

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

David keeps a range of stationery in his study.

Let the pencil is represented by x.

Let the erasers be represented by y.

Let the pens be represented by z.

Let n be the stationery.

5/7 of his stationery consists of pencils.

x = 5/7 n

1/6 of the remaining stationery consists of erasers.

y = 1/6 n

There are 20 pens in his study.

z = 20
