Explanation:
If y = 3² × 5³, then y³ can be calculated by raising y to the power of 3.
y³ = (3² × 5³)³
Using the rules of exponents, we can expand this expression:
y³ = 3²³ × 5³³
Simplifying further:
y³ = 9³ × 125³
Calculating the powers:
y³ = 729 × 1,953,125
Multiplying:
y³ = 1,421,959,375
Therefore, y³ is equal to 1,421,959,375.
