[tex]
\frac{\sqrt[4]{4000} \times 75.9}{5.61 \times 4.39}
[/tex]



Answer :

Sure, let's evaluate the given expression step by step:

Given expression:
[tex]\[ \frac{\sqrt[4]{4000} \times 75.9}{5.61 \times 4.39} \][/tex]

1. Calculate the fourth root of 4000:

To find the fourth root of [tex]\( 4000 \)[/tex], we need to find a number [tex]\( x \)[/tex] such that [tex]\( x^4 = 4000 \)[/tex]. The fourth root of [tex]\( 4000 \)[/tex] is approximately:
[tex]\[ \sqrt[4]{4000} \approx 7.9527 \][/tex]

2. Multiply the fourth root of 4000 by 75.9:

Next, we multiply [tex]\( 7.9527 \)[/tex] by [tex]\( 75.9 \)[/tex]:
[tex]\[ 7.9527 \times 75.9 \approx 603.6105 \][/tex]

3. Calculate the product of the denominators [tex]\( 5.61 \)[/tex] and [tex]\( 4.39 \)[/tex]:

We multiply [tex]\( 5.61 \)[/tex] by [tex]\( 4.39 \)[/tex]:
[tex]\[ 5.61 \times 4.39 \approx 24.6279 \][/tex]

4. Divide the result of the numerator by the result of the denominator:

Finally, we divide [tex]\( 603.6105 \)[/tex] by [tex]\( 24.6279 \)[/tex]:
[tex]\[ \frac{603.6105}{24.6279} \approx 24.5092 \][/tex]

Hence, the evaluated result of the expression is approximately:
[tex]\[ \frac{\sqrt[4]{4000} \times 75.9}{5.61 \times 4.39} \approx 24.5092 \][/tex]
