CONCEPT PREVIEW Perform the indicated operation, and write each answer in lowest terms (2x/5) • (10/x²)

Guida verificata passo dopo passo
1
Rewrite the given expression clearly: \(\frac{2x}{5} \cdot \frac{10x}{x^{2}}\).
Multiply the numerators together and the denominators together: \(\frac{2x \times 10x}{5 \times x^{2}}\).
Simplify the numerator by multiplying the coefficients and variables: \(2 \times 10 = 20\) and \(x \times x = x^{2}\), so numerator becomes \$20x^{2}$.
Simplify the denominator: \(5 \times x^{2} = 5x^{2}\).
Write the fraction as \(\frac{20x^{2}}{5x^{2}}\) and then simplify by canceling common factors in numerator and denominator.
