Impara online a risolvere i problemi di passo dopo passo. m=(7^(1/2)+2)(5^(1/2)+1)(5^(1/2)-1)(7^(1/2)-2). Applicare la formula: \left(a+b\right)\left(a+c\right)=a^2-b^2, dove a=\sqrt{7}, b=2, c=-2, a+c=\sqrt{7}-2 e a+b=\sqrt{7}+2. Applicare la formula: \left(a+b\right)\left(a+c\right)=a^2-b^2, dove a=\sqrt{5}, b=1, c=-1, a+c=\sqrt{5}-1 e a+b=\sqrt{5}+1. Applicare la formula: a+b=a+b, dove a=7, b=-4 e a+b=7-4. Applicare la formula: a+b=a+b, dove a=5, b=-1 e a+b=5-1.
