Question

Evaluate the algebraic expression if a=4,b=5,
$\frac{ {a}^{3} - {b}^{2} }{ - 13}$
​

Answer 1

Answer:

-3

Step-by-step explanation:

a =4 , b =5

then,

( 4^3 - 5^2 )/-13

(64-25) /-13

39/-13

3/-1

-3

Answer 2

$\huge\bigstar\underline{\underline\pink{Question:-}}$

Evaluate the algebraic expression if a=4,b=5,

$\huge \frac{ {a}^{3} - {b}^{2} }{ - 13}$ = ?

$\huge\bigstar\underline{\underline\pink{Answer:-}}$

$\sf\underline{\underline\pink{Given:}}$

$\orange\rightarrow$ a value = 4

$\orange\rightarrow$ b value = 5

$\sf\underline{\underline\pink{To find:}}$

$\huge\frac{ {a}^{3} - {b}^{2} }{ - 13}$

$\bf\underline{\underline\pink{Solution:}}$

$\orange\Rightarrow$ $\huge \frac{ {a}^{3} - {b}^{2} }{ - 13}$

$\orange\Rightarrow$ $\huge \frac{ {4}^{3} - {5}^{2} }{ - 13}$

$\orange\Rightarrow$ $\huge\frac{{64} - {25}} {-13}$

$\orange\Rightarrow$ $\huge\frac {39}{-13}$

$\orange\Rightarrow$$\huge{ -3}$

$\sf\orange\therefore$ The value of the given algebraic expression is -3.
