how would the expression x^3+18 be re written using the sum of cubes
Accepted Solution
A:
Answer: are you sure it is 18, and not some number like 27?Step-by-step explanation:the sum of cubes is a^3 + b^3 = (a+b) (a^2+ab+b^2) the a and b must be able to be expressed in a cube form such as x^3, but there is no cube root of 18.27 for example does have it. 3^3 because 3*3*3=27 so it could be expressed as X^3 and 3^3 which would follow that form above. X being the a and the 3 being the b. hope this helped, have a great day!
