Question

Please help me solve this math problem

Answer 1

The answer is: 8^-5

Explanation: When two numbers with the same base (in this case, the base is 8) are multiplied, you add the exponents. 4 + (-9) = -5. Therefore, The answer is 8^-5.

Answer 2

`\sf 8^(-5)`

Explanation:

To Simplify:

`\sf 8^4 \cdot 8^(-9)`

Solution:

In order simplify this, we can use the following rule of exponents which state that mathematically:

`\sf x^m \cdot x^n = x^(m+n)`

Therefore, we have:

`\sf 8^4 \cdot 8^(-9) = 8^(4-9) = 8^(-5)`

So, Answer is:

`\sf 8^(-5)`
