What is the algebraic expression for "4 less than the cube of a number and 3"?????? tell me why???

Question

Which is clearer???
Four less than cubed of a number and three. Please give me the algebraic expression. I believe they're the same

Answer 1

"a number and 3" = x + 3

"the cube of a number and 3" = (x + 3)^3

"4 less than the cube of a number and 3" = (x + 3)^3 - 4

this might be called a translation from english to mathematics

Answer 2

Lets rephrase the expression as "4 less than the cube of the sum of a number and 3". Thus, it is quite clear.

(x+3)^3 - 4

Answer 3

I'm not positive I understand your question.
4 less than the cube of a number can be re-written "the cube of a number minus 4"
let the number be x

Then the expression is "the cube of x minus 4", or x^3 - 4

The part I don't understand is the "and three" part.

Answer 4

Let x be the number in question.

Then, the cube of a number would be x^3.

"4 less than the cube of a number" means

x^3 - 4

The word problem may be interpreted ambiguously, but if "the cube of a number and 3" is meant to be lumped together, you would then have

(x + 3)^3 - 4

Answer 5

okay.. lets say that "a number" is x... so 4 less than the cube and 3 wud be
(x^3 + 3) - 4
the and 3 part is indeed confusing... because ur question can also be interpreted as (X^3-4) + 3
Also... another way wud be (x + 3)^3 - 4...
