Use exponents to condense the expression below.

x, dot, x, dot, x, dot, x, dot, x, dot, y, dot, y, dot, y, dot, y, dot, z, dot, z, dot, z
x⋅x⋅x⋅x⋅x⋅y⋅y⋅y⋅y⋅z⋅z⋅z

To condense the expression xxxxxyyyyzzz using exponents, we count the number of times each variable appears:

  • The variable x appears 5 times, which can be written as x5.
  • The variable y appears 4 times, which can be written as y4.
  • The variable z appears 3 times, which can be written as z3.

Putting this all together, the condensed expression is:

x5y4z3

If desired, this can also be written as:

x5y4z3

This represents the same quantity without the dots.
