Q. Evaluate the expression

5\cdot \frac{x^3}{x^2}

for

x=2

Substitute $x$ into expression: Substitute the value of $x$ into the expression. $\newline$ Substitute $x = 2$ into the expression $5\cdot x^3/x^2$ . $\newline$ $5\cdot(2^3)/(2^2)$
Simplify powers of x: Simplify the powers of $x$ . $\newline$ Calculate $2^3$ and $2^2$ . $\newline$ $2^3 = 2 \times 2 \times 2 = 8$ $\newline$ $2^2 = 2 \times 2 = 4$ $\newline$ Now the expression is $5\times8/4$ .
Perform multiplication and division: Perform the multiplication and division. $\newline$ Multiply $5$ by $8$ to get $40$ . $\newline$ Then divide $40$ by $4$ to get the final result. $\newline$ $40/4 = 10$
