After joining two pieces of a picture frame together, a frame maker checks her work by measuring the diagonal. the sides of the frame form a right angle and the measurements are as follows: a = 12 in. and b = 5 in

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218
