\left(\frac{5\times 2x}{15}+\frac{3\times 4x}{15}\right)^{2}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 3 and 5 is 15. Multiply \frac{2x}{3} times \frac{5}{5}. Multiply \frac{4x}{5} times \frac{3}{3}.
\left(\frac{5\times 2x+3\times 4x}{15}\right)^{2}
Since \frac{5\times 2x}{15} and \frac{3\times 4x}{15} have the same denominator, add them by adding their numerators.
\left(\frac{10x+12x}{15}\right)^{2}
Do the multiplications in 5\times 2x+3\times 4x.
\left(\frac{22x}{15}\right)^{2}
Combine like terms in 10x+12x.
\frac{\left(22x\right)^{2}}{15^{2}}
To raise \frac{22x}{15} to a power, raise both numerator and denominator to the power and then divide.
\frac{22^{2}x^{2}}{15^{2}}
Expand \left(22x\right)^{2}.
\frac{484x^{2}}{15^{2}}
Calculate 22 to the power of 2 and get 484.
\frac{484x^{2}}{225}
Calculate 15 to the power of 2 and get 225.
