If x=y=2z and xyz= 256, then x = ?
From the given information, we know that:
- x = y = 2z (equation 1)
- xyz = 256 (equation 2)
Substituting equation 1 into equation 2, we get:
(2z)(2z)(z) = 256
Simplifying this expression, we get:
4z3 = 256
Dividing both sides by 4, we get:
z3 = 64
Taking the cube root of both sides, we get:
z = 4
Substituting z = 4 into equation 1, we get:
x = y = 2(4) = 8
Therefore, x = 8.
সমাধান
given that,
y = x
2z = x
ATQ,
xyz = 256
or, x × y × 2z = 256 × 2
or, x × x × x = 512
or, x3 = 83 [ Speed Calculation ]
∴ x3 = 8
