Impara online a risolvere i problemi di passo dopo passo. Expand and simplify the trigonometric expression (cos(x)^2+4sin(y)^2)^3. Applicare la formula: \left(a+b\right)^3=a^3+3a^2b+3ab^2+b^3, dove a=\cos\left(x\right)^2, b=4\sin\left(y\right)^2 e a+b=\cos\left(x\right)^2+4\sin\left(y\right)^2. Applicare la formula: ab=ab, dove ab=3\cdot 4\left(\cos\left(x\right)^2\right)^2\sin\left(y\right)^2, a=3 e b=4. Applicare la formula: \left(x^a\right)^b=x^{ab}, dove a=2, b=3, x^a^b=\left(\cos\left(x\right)^2\right)^3, x=\cos\left(x\right) e x^a=\cos\left(x\right)^2. Applicare la formula: ab=ab, dove ab=2\cdot 3, a=2 e b=3.
