fourth proportional to:
st⁵, s²t³, s³t²
Let the terms be:
A = st⁵
B = s²t³
C = s³t²
D = ?
In fourth proportion, the relation is:
A : B = C : D
So, D = (B × C) / A
Now plug in the values:
B × C = (s²t³) × (s³t²) = s⁵t⁵
A = st⁵
Now divide:
D = (s⁵t⁵) / (st⁵) = s⁴
So, the fourth proportional is s⁴
✅ Correct answer: 4. s⁴
चौथा आनुपातिक:
st⁵, s²t³, s³t²
पदों को इस प्रकार मान लें:
A = st⁵
B = s²t³
C = s³t²
D = ?
चौथे आनुपातिक में, संबंध है:
A : B = C : D
तो, D = (B × C) / A
अब मान डालें:
B × C = (s²t³) × (s³t²) = s⁵t⁵
A = st⁵
अब विभाजित करें:
D = (s⁵t⁵) / (st⁵) = s⁴
तो, चौथा आनुपातिक s⁴ है
✅ सही उत्तर: 4. s⁴
