(?) solve the following. please show your steps !! a. 100 – 8 × √25 + 3?

b. 100 – (11 – 4)² × 2?

Use PEDMAS for order of operation:

a: 100 – 8 × √25 + 3

First solve the root:

100 – 8 × 5 + 3

Next multiply:

100 - 40 + 3

Now solve from left to right:

100-40 = 60

60+3 = 63

63

b. 100 – (11 – 4)² × 2

First parentheses:

100 - 7^2 x 2

Next the power:

100 - 49 x 2

Multiplication:

100 - 98 = 2
