Ms. P made a mistake when she simplified the problem below. Find, describe, and correct Ms. P’s mistake.
[(8 ¸ 1 – 3)3 – (3 + 7)] - 1
[(8 -3)3 – (3 + 7)] – 1
[(5)3 – (3 + 7)] – 1
[15 – 10] – 1
5 – 1

1.) 1 ¸ {[ 5 – (3 – 1)2] ¸ (3 ¸ 3)}
2.) [ 1 + 4 + 5 x 1 – (6 + 2)]4
3.) [( 9 + 9) ¸ 9]3 - 4
4.) {4 ¸ [4 – (1 + 5 ¸ 5)]}4
5.) Circle the line with the mistake then simplify the expression correctly
5 x 4 ¸ (5 ¸ 5) - 24
