Proceed with the division lim 5+3/x+10/x²=5+0+0= 5 b. is the correct one. x→+∞ We use the theorem limit of a sum is the sum of limits.

If this is (5x^3 + 3x^2 + 10x) / x^3, the limit is 5. B). Degrees of numerator and denominator are equal, so the quotient of the leading coefficients is the limit.

Why is this math question being moved to R&S?

It's a trick question. Beware of the rule, Order of Operations:1st, exponents and roots; 2nd, multiplication and division; 3rd, addition and subtraction. The answer is: x → 0.

I assume you mean (5x^3 + 3x² + 10x)/(x^3), so as x -> ∞, you have 5(x^3)/x(^3) = 5, so B

Okay, I tried to be nice and put this in Mathematics where it belongs. Would you care to tell me why it's back here?

B Divided by x^3 it becomes 5+3/x+10/x^2 And put in x as infinity, the ones divided by x are zero Assuming you forgot to put out parentheses and meant (5x^3+3x^2+10x)/x^3
