Hello!

Cube = x³

The sum of any two numbers = x + y

Half = ÷2

So the algebraic expression is going to be (\frac{x+y}{2} )^{3}

    Hope it helps! :))

Answer:

The algebraic expression representing the statement 'The cube of half of the sum of any two numbers' = = \frac{x^3}{8} +\frac{y^3}{8} + \frac{3x^2y}{8} +\frac{3xy^2}{8}

Step-by-step explanation:

Required to find,

An algebraic expression representing the statement 'The cube of half of the sum of any two numbers'

Solution:

'x' and 'y' be the numbers

Sum of the two numbers = x+y

Half of the sum of the two numbers = \frac{x+y}{2}

The cube of the half of the sum of the two numbers = (\frac{x+y}{2})^3

(\frac{x+y}{2})^3 = \frac{1}{8}[x³ +y³ + 3x²y+3xy²]

= \frac{x^3}{8} +\frac{y^3}{8} + \frac{3x^2y}{8} +\frac{3xy^2}{8}

∴The algebraic expression representing the statement 'The cube of half of the sum of any two numbers' = = \frac{x^3}{8} +\frac{y^3}{8} + \frac{3x^2y}{8} +\frac{3xy^2}{8}
