When [tex]$1,250^{\frac{3}{4}}$[/tex] is written in its simplest radical form, which value remains under the radical?

A. 2
B. 5
C. 6
D. 8



Answer :

To express [tex]\( 1250^{\frac{3}{4}} \)[/tex] in its simplest radical form, let's break the problem into smaller steps.

1. Prime Factorization:
Start with the prime factorization of 1250.
[tex]\[ 1250 = 125 \times 10 = 5^3 \times 2 \times 5 = 5^4 \times 2 \][/tex]

2. Exponentiation:
We have the expression [tex]\( 1250^{\frac{3}{4}} \)[/tex]. Using our factorization, we can write:
[tex]\[ (5^4 \times 2)^{\frac{3}{4}} \][/tex]

3. Distribute the exponent:
Apply the exponent to each part separately:
[tex]\[ (5^4)^{\frac{3}{4}} \times 2^{\frac{3}{4}} \][/tex]

4. Simplify each term:
Simplify each part of the expression:
[tex]\[ (5^4)^{\frac{3}{4}} = 5^{4 \times \frac{3}{4}} = 5^3 \][/tex]
And,
[tex]\[ 2^{\frac{3}{4}} \][/tex]

5. Combine the results:
Combine the simplified terms back together:
[tex]\[ 5^3 \times 2^{\frac{3}{4}} \][/tex]

So, the expression [tex]\( 1250^{\frac{3}{4}} \)[/tex] in its simplest radical form can be written as:
[tex]\[ 5^3 \sqrt[4]{2^3} \][/tex]

In this form, the value that remains under the radical is associated with the term [tex]\( 2^{3/4} \)[/tex], and it involves the number 2.

Thus, the value that remains under the radical is:
[tex]\[ \boxed{2} \][/tex]
