# What is the value of n3 equals 8000?

N^3=8000

Take the cube root of N, and do it to the 8000

N=20

Because 20x20x20=8000

### How do you find the smallest positive integer of a variable in a cube root so that the cube root is an integer ex. find the smallest positive integer g so that the cube root of 400g is an integer?

Here is a method: cube root of 400g = n, where n is an integer cube both sides: 400g = n3 then: g = n3/400 therefore: n3/400 must be an integer if this is so, then n3 must be divisible by 400 with no remainder, and n must be => cube root of 400 which is 7.368 bracket the answer by substitution: let n=8, n cubed = 512 no good let n=12, n cubed =…

### What does Fortran statement If left paren If left paren 2 times A comma Y Rt paren Rt paren 6 comma 5 comma 6 mean?

It is a three-way case statement. ( Arithmetic IF statement) IF(exp) n1,n2,n3 meaning go to n1 if expr < 0 ( value is negative) go to n2 if expr = 0 ( value is zero) go to n3 if expr > 0 ( value is positive) IF(expr1-expr2) n1,n2,n3 meaning go to n1 if expr < expr2 go to n2 if expr = expr2 go to n3 if expr > expr2 reference: Fortran 77 with 90…
