Question

find the value of r(1/2)​

Answer 1

this is value is very simple. answer is r upon 2

Answer 2

Answer:

Required value is $\frac{r}{2}$

Step-by-step explanation:

Here given

$r( \frac{1}{2} )$

$= r \times \frac{1}{2}$

We are multiplying r and $\frac{1}{2}$

$= \frac{r}{2}$

This is problem of Algebra.

Some important formulas of Algebra,

a + b)² = a² + 2ab + b²

(a − b)² = a² − 2ab − b²

(a + b)³ = a³ + 3a²b + 3ab² + b³

(a - b)³ = a³ - 3a²b + 3ab² - b³

a³ + b³ = (a + b)³ − 3ab(a + b)

a³ - b³ = (a -b)³ + 3ab(a - b)

${a}^{2} - {b}^{2} = (a + b)(a - b)$

${a}^{2} + {b}^{2} = {(a + b)}^{2} - 2ab$

${a}^{2} + {b}^{2} = {(a - b)}^{2} + 2ab$

${a}^{3} - {b}^{3} = (a - b)( {a}^{2} + ab + {b}^{2} )$

${a}^{3} + {b}^{3} = (a + b)( {a}^{2} - ab + {b}^{2} )$
