Answer 1

• No 3.)

(6 - 2³) × ( - 3 )

= (6 - (2 × 2 × 2)) × ( - 3 )

= (6 - 8) × ( - 3 )

= - 2 × ( - 3 )

=> 6

• No 4.)

( - 4 )² + 25 ÷ ( - 5 )²

= ( -4 × -4 ) + 25 ÷ ( -5 × -5 )

= 16 + 25 ÷ 25

= 16 + 1

=> 17

• No 5.)

√16 × ( - 3 )³ + ( - 7 )²

= ²√4² × ( - 27 ) + 49

= 4 × ( - 27 ) + 49

= - 108 + 49

=> - 59

• No 6.)

- 33 ÷ 3 × √25 - 6²

= - 33 ÷ 3 × ²√5² - 36

= - 33 ÷ 3 × 5 - 36

= - 11 × 5 - 36

= - 55 - 36

=> - 91
