Figure 1 shows the circuit diagram of inverting op-amp
$A_V$ is given by, $$|A_v| = \frac{-R_F}{R_1}$$ Since $|A_V|$=10, where $A_V$ is negative but by taking mod we write it in positive,
$$-10 = \frac{-R_F}{R_1}$$
Assume $R_1$ = 1KΩ hence,
$$-10 × 1KΩ = $-R_F$$
$$R_F = 10KΩ$$ Hence, designed circuit …
