The sum of the factors of what perfect cube is 400?

Cube root of 400 can be represented as 3√400. The value of cube root of one is 400.The nearest previous perfect cube is 343 and the nearest next perfect cube is 512 .

Step-by-step explanation:

343

Step-by-step explanation:

Let the perfect cube be x³.

The factors of this cube is 1, x, x², x³

According to question,

The sum of the factors should be equal to 400.

So,

1 + x + x² + x³ = 400

By using hit and trial method,

The value of x comes out be 7

So, the perfect cube whose factors have a sum of 400 is the cube of the number, 7 = 7³ = 343

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

answer: 0,6

step-by-step explanation:

this would make it the y intercept.
