Impara online a risolvere i problemi di passo dopo passo. Solve the product (r-1)(r-1)(r-1). Applicare la formula: x\cdot x=x^2, dove x=r-1. Applicare la formula: x\cdot x^n=x^{\left(n+1\right)}, dove x^nx=\left(r-1\right)^2\left(r-1\right), x=r-1, x^n=\left(r-1\right)^2 e n=2. Applicare la formula: a+b=a+b, dove a=2, b=1 e a+b=2+1. Applicare la formula: \left(a+b\right)^3=a^3+3a^2b+3ab^2+b^3, dove a=r, b=-1 e a+b=r-1.
