Answer 1

3⁻⁵   3⁻⁷ : 3⁻¹⁵ = 3⁽⁻⁵⁻⁷) : 3⁻¹⁵ = 3⁻¹² : 3⁻¹⁵ = 1/3⁻³ = 3³ = 27

Answer 2

Sure, I'd be happy to help you with this mathematical expression.

Let's simplify the expression step by step:

1. Start with the numerator: 3^(-5) * 3^(-7)

When you multiply two numbers with the same base and different exponents, you can add the exponents:

3^(-5) * 3^(-7) = 3^(-5 - 7) = 3^(-12)

2. Now, move on to the denominator: 3^(-15)

3. Combine the simplified numerator and denominator: 3^(-12) / 3^(-15)

When you divide two numbers with the same base and different exponents, you can subtract the exponent of the denominator from the exponent of the numerator:

3^(-12) / 3^(-15) = 3^(-12 - (-15)) = 3^(-12 + 15) = 3^3

Now, the expression is simplified to 3^3.

Finally, calculate 3^3:

3^3 = 3 * 3 * 3 = 27

So, the final result of the expression 3^(-5) * 3^(-7) / 3^(-15) is 27.
