In an algebraic expression, terms are separated by plus or minus signs.

The term coefficient refers to the number in front of the variable in any term of the expression.

A constantterm is the number which have no variable associated with it.

Like terms are the terms which have identical variable parts with same exponent on it. Constants are considered to be like terms as well.

Distributive property: $a\left(b+c\right)=a·b+a·c$

The cube of a number $x$is 2744

The cube of the largest single digit number 9 is $729$, which is a three digit number.

Thus, $x$is a two digit number.

Now, lets check for x as 11

$\begin{array}{l}{11}^3=11×11×11\\ =121×11\\ =1331\end{array}$

Similarly, for x = 12

$\begin{array}{l}{12}^3=12×12×12\\ =144×12\\ =1728\end{array}$

For x as 13, we get

$\begin{array}{l}{13}^3=13×13×13\\ =169×13\\ =2197\end{array}$

And for x=14 we have

$\begin{array}{l}{14}^3=14×14×14\\ =196×14\\ =2744\end{array}$

Hence, $x=14$is the number whose cube is 2744.
