Answer 1

$\huge{\boxed{\mathtt{\purple{Answer}}}}$

Let the numbers be 4x and 5x.
As per given condition we have,
(5x)³-(4x)³=61

125x³-64x³=61

61x³=61

x³=61/61

x³=1

x=1
Now,
4x=4×1=4
5x=5×1=5

Answer 2

Answer:

sorry,it is correct answer.

Step-by-step explanation:

Let the numbers be 4x and 5x.

(5x)^3-(4x)^3 = 61

=> (125)x^3-(64)x^3=61

=> (61)x^3=61

=> (x)^3=61/61

=> (x)^3=1

=> x=1
