Answer:
To simplify 9 to the power of -8 multiplied by 9 to the power of 5 using a single positive exponent, we can apply the rule of exponentiation.
The rule states that when you multiply two numbers with the same base, you can add their exponents.
In this case, we have 9 to the power of -8 multiplied by 9 to the power of 5.
Using the rule, we can add the exponents together: -8 + 5 = -3.
Therefore, 9 to the power of -8 multiplied by 9 to the power of 5 is equal to 9 to the power of -3.
