Step-by-step explanation:first you put the x and apply cube in the ratio

4:5 = (4x)^3:(5x)^3

(5x)^3 – (4x)^3 = 61

125x – 64x = 61

61x = 61

x = 61÷61

x = 1

4x = 4×1 = 4

5x = 5×1 = 5

let prove it and check it is 0 or not –

(5)^3 – (4)^3 = 61

125 – 64 = 61

61 = 61

=61 – 61

= 0

let it is correct
