Answer:

the answer is incorrect though  the first step is correct but the second step is wrong and so is the answer. the correct answer would be x raise to the power of 2by 5

Step-by-step explanation:

{x⁶/⁵⁻²/⁵} ¹/²= {x⁴/⁵}¹/²= x²/⁵

in the second step the power of the denominator must be subtracted from the power of the numerator using the law of indices then we would get the correct answer

Using arc length formula find s when r=24 and θ=π/2<br><br> 48π<br> 24π<br> 12π
bulgar [2K]

Answer:

12π

Step-by-step explanation:

The formula for arc length is given as:

s = \frac{\theta}{360\degree} \times 2\pi r

Plug r = 24 and θ=π/2 in the above formula, we fi d:

s = \frac{\frac{\pi}{2}}{360\degree} \times 2\pi \times 24\\\\s = \frac{\frac{\pi}{2}}{2 \pi} \times 48\pi\\\\s = \frac{\pi}{2\times 2 \pi} \times 48\pi \\\\s = \frac{\pi}{4\pi} \times 48\pi \\\\\huge \purple {\boxed{s = 12\pi}} \\
