Question

.if 3m = 2n then find value of : (7n²- 4m²) / (7n²+4m²) .​

Answer 1

Question:

if 3m = 2n then find value of : (7n²- 4m²) /(7n²+4m²) .

Given Information:

3m = 2n

Then, we can say that

m= 2/3×n

n= 3/2×m

To Find:

(7n²- 4m²) /(7n²+4m²)

Solution:

(7×9/4×m²-4m²) /(7×4/9×n²+4m²)

(63/4×m²-4m²)/(28/9n²+4m²)
