x^-7•x^9•x^-3

Write your answer with a positive exponent only

x^-7 • x^9 • x^-3 = x^(-7 + 9 - 3)

= x^-1

To simplify the expression x^-7 • x^9 • x^-3, we can add the exponents of the x terms. This can be done because when we multiply two terms with the same base, we can add their exponents:

x^-7•x^9•x^-3 = x^(-7 + 9 - 3)

Simplifying further, we get:

x^(-7 + 9 - 3) = x^(-1)

So, the simplified expression with a positive exponent is x^-7 • x^9 • x^-3 = x^(-1).

To simplify the expression x^-7 • x^9 • x^-3, we can use the rule of adding exponents when multiplying like bases.

First, let's combine the x terms by adding the exponents:
x^-7 • x^9 • x^-3 = x^(-7 + 9 - 3)

Next, simplify the exponent inside the brackets:
= x^(-1)

Since the exponent is negative, we can rewrite it as a positive exponent by taking the reciprocal:
= 1/x^1

Finally, we can simplify the expression further by removing the exponent of 1:
= 1/x

Therefore, the expression x^-7 • x^9 • x^-3 simplifies to 1/x.
