Question

(5/9)³ + (5/9)² = (9/5)-n​

Answer 1

${( \frac{5}{9} )}^{3} \: +{ ( \frac{5}{9} )}^{2} = ( \frac{9}{5} ) - n$

Step 1: Simplify both sides of the equation.

(5/9)^3+(5/9)^2= (9/5)−n

125/729+25/81=9/5+−n

(125/729+25/81)=−n+9/5

(Combine Like Terms)

350/729=−n+9/5

350/729=−n+9/5

Step 2: Flip the equation.

−n+9/5=350/729

Step 3: Subtract 9/5 from both sides.

−n+9/5−9/5=350/729−9/5

−n=−4811/3645

Step 4: cancel "-" both sides

−n=−481/3645

n=4811/3645

hope it helps....
