Question

In a five digit number 24yx9, x is the greatest single digits perfect cube and x exceeds twice of y by 2. The difference of the number and it's cube root is-

Answer 1

Answer:

$29$

Explanation:

we have 24yx9

x is greatest single digit perfect cube .so x is 8 which is only single digit perfect cube.

x=8..............1

by data x exceeds twicw of the y by 2..

so: x=2y+2

8 = 2y + 2

y = 3.............2

now we got both tje values of x and y

so the number will be

24389

$\sqrt[3]{24389} = 29$

$\sqrt[3]{24689 } = 29$
