Refer to expression 1 and expression 2. expression 1: 6 * 7 - 3^2 * 9 + 4^3 expression 2: 5 + 4 * 2 + 6 - 2 * 2 -1 (a) what is the value of expression 1? (b) insert parentheses in expression 2 so that it has a value of 19. then show why your expression has a value of 19.

(a)What is the value of Expression 1?
Expression 1: 6 * 7 - 3^2 * 9 + 4^3

6 * 7 - 3^2 * 9 + 4^3
= 42 - 81 + 64
= 25

(b)Insert parentheses in Expression 2 so that it has a value of 19. Then show why your expression has a value of 19.

Expression 2: 5 + 4 * 2 + 6 - 2 * 2 -1

(5 + 4) * 2 + 6 - (2 * 2) -1
