Using PEDMAS, the value of each expressions are:
a. 1 + 5 × 2 + (1 + 3)² = 27
b. 0.25 × 4³ - 1 = 15
c. 4 + 8(1/4 + 2) = 22
PEDMAS implies that you solve a problem first following the order, parentheses, exponent, division, multiplication, addition, and subtraction.
Let's evaluate the expressions using PEDMAS:
a. 1 + 5 × 2 + (1 + 3)²
1 + 5 × 2 + (4)²
1 + 5 × 2 + 16
1 + 10 + 16
= 27
b. 0.25 × 4³ - 1
0.25 × 64 - 1
16 - 1
= 15
c. 4 + 8(1/4 + 2)
4 + 8(9/4)
4 + 18
= 22.
