first

X X X X = {(X)}^{4}

thus

5 X X X X = 5 {(X)}^{4}

second

7 Y \cdot 7 Y \cdot 7 Y = {(7 Y)}^{3}

third

r r = {(r)}^{2}

2 t \cdot 2 t \cdot 2 t = {(2 t)}^{3}

thus

r r \cdot 2 t \cdot 2 t \cdot 2 t = {(r)}^{2} \cdot {(2 t)}^{3}

answer

5 {(X)}^{4} .

{(7 Y)}^{3} .

{(r)}^{2} \cdot {(2 t)}^{3} .
