A) √ X = 4 ---> X = 4 ² ----> X = 16
B) √ X = 7 ---> X = 7² ----> X = 49
C) √ X = 13 -----> X = 13² ---> X = 169
D) √ X = 20 ----> X = 20² -----> X = 400
E) ³√ X = 5 ----> ( ³√ X )³ = 5³ ----> X = 5³ ---> X = 125
F) 4 . √ X = 3 ----> √ X = ( 3/4) ---> X = ( 3/4)² ----> X = 9/16
G) ³√ X = - 2 ----> X = ( - 2 )³ ----> X = -8
H) 5 √ X = -1 ----> √ X = -1/5 ---> X = ( -1/5)² ---> X = 1/25
B) √ X = 7 ---> X = 7² ----> X = 49
C) √ X = 13 -----> X = 13² ---> X = 169
D) √ X = 20 ----> X = 20² -----> X = 400
E) ³√ X = 5 ----> ( ³√ X )³ = 5³ ----> X = 5³ ---> X = 125
F) 4 . √ X = 3 ----> √ X = ( 3/4) ---> X = ( 3/4)² ----> X = 9/16
G) ³√ X = - 2 ----> X = ( - 2 )³ ----> X = -8
