The prime-power representation of 48,400 is \( 2^{4} \cdot 5^{2} \cdot 11^{1} \). To check which numbers are squares, we can analyze their prime-power representations. A number is a perfect square if all the exponents in its prime-power representation are even. Therefore, \( 59,930,332 \) has exponents of \( 2, 3, 2, 2 \) (not all even, so not a square). For \( 48,400 \), \( 4, 2, 1 \) (again, not all even, so not a square). The number \( 1,882,384 \) has a prime-power representation of \( 2^{6} \cdot 3^{1} \cdot 7^{2} \) (not a square either since 1 is odd). For part (e), a perfect square in prime-power representation simply means that each prime factor's exponent is even. For part (f), \( 27,543,608 \)’s representation allows for quick identification as a cube if all the exponents are multiples of 3, making it easy to spot a potential cube by just looking at the numbers.
