Question

Help me please!!!!!!!!

Answer 1

Answer:

1) 4

2) 1.5

3) 8

4) 1

5) 5

6) 9

Step-by-step explanation:

1)

√16

= √(4x4)

= √(4)²

= 4

2)

√2.25

= √(9/4)

= √(3x3)/(2x2)

= √(3)²/(2)²

= 3/2

= 1.5

3)

6² ÷ 9 x 2

= 36 ÷ 9 x 2

= 36 x 1/9 x 2

= 36/9 x 2

= 12/3 x 2

= 4 x 2

= 8

4)

12-2 / 6+4

= 10/10

= 1

5)

√(16+9)

= √(25)

= √(5x5)

= √(5)²

= 5

6)

63 ÷ 3² + |2|

= 63 ÷ 9 + |2|

= 63/9 + |2|

= 21/3 + |2|

= 7 + |2|

= 9
