=LOGNORM.INV()
Returns the inverse of the lognormal cumulative distribution function of x, where ln(x) is normally distributed with parameters Mean and Standard_dev. If p = LOGNORM.DIST(x,...) then LOGNORM.INV(p,...) = x. Use the lognormal distribution to analyze logarithmically transformed data.

Result:
4.0000252
§ Remarks
- If any argument is nonnumeric, LOGNORM.INV returns the #VALUE! error value.
- If probability <= 0 or probability >= 1, LOGNORM.INV returns the #NUM! error value.
- If standard_dev <= 0, LOGNORM.INV returns the #NUM! error value.
⚠ Common Errors
#VALUE!
If any argument is nonnumeric, LOGNORM.INV returns the #VALUE! error value.
Fix: برای تمام آرگومانها مقدار عددی وارد کنید.
#NUM!
If probability <= 0 or probability >= 1, LOGNORM.INV returns the #NUM! error value. If standard_dev <= 0, LOGNORM.INV returns the #NUM! error value.
Fix: Correct the input value
