The expression of (5a³ⁿ)³ in positive exponents using the law of indices is 125 a⁹ⁿ
The expression has exponents. Therefore, let's express it with a positive exponent.
Therefore,
(5a³ⁿ)³
Hence, let distribute the outside exponents(law of indices),
(5a³ⁿ)³ = 5³ × a³ⁿ ˣ ³
Therefore,
5³ × a³ⁿ ˣ ³
5 × 5 × 5 = 5³ = 125
a³ⁿ ˣ ³ = a⁹ⁿ
Hence,
(5a³ⁿ)³ = 125 a⁹ⁿ

The area of the circle with a radius of 20m is 400π square meters.
The formula to find the area of a circle is π * radius2. Given that the radius is 20m, we can substitute it into the formula: Area = π * (20m)2. This simplifies to 400π m2. Therefore, the correct answer is 400π m2.
