(4/9)^-1= A. -4/9 B. 9/4 C. -9/4

Romashka-Z-Leto [24]

Answer: 9/4

Step-by-step explanation: Think of $(\frac{4}{9})^{-1}$ as $\frac{4^{-1} }{9^{-1}}$ .

Now, we can change 4⁻¹ to 4¹ by moving it to the denominator and

we can change 9⁻¹ to 9¹ by moving it to the numerator.

So we have 9¹/4¹ which simplifies to 9/4.
