Questions and Answers

Q 1 - Evaluate the expression (15 − 7)2 ÷ 16

A - 2

B - 3

C - 4

D - 5

Answer : C

Explanation

Step 1:

Simplifying the parantheses

(15 − 7)2 ÷ 16 = (8)2 ÷ 16

Step 2:

Simplifying the exponent

(8)2 ÷ 16 = 64 ÷ 16

Step 3:

Doing division

64 ÷ 16 = 4

Step 4:

So (15 − 7)2 ÷ 16 = 4

Q 2 - Evaluate the expression 18 + 32 ÷ 24

A - 20

B - 22

C - 24

D - 32

Answer : A

Explanation

Step 1:

Simplifying the exponent

18 + 32 ÷ 24 = 18 + 32 ÷ 16

Step 2:

Doing division

18 + 32 ÷ 16 = 18 + 2

Step 3:

Doing addition

18 + 2 = 20

Step 4:

So 18 + 32 ÷ 24 = 20

Q 3 - Evaluate the expression (9 − 5)4 ÷ 32

A - 6

B - 8

C - 16

D - 24

Answer : B

Explanation

Step 1:

Simplifying the parentheses

(9 − 5)4 ÷ 32 = (4)4 ÷ 32

Step 2:

Simplifying the exponent

(4)4 ÷ 32 = 256 ÷ 32

Step 3:

Doing division

256 ÷ 32 = 8

Step 4:

So (9 − 5)4 ÷ 32 = 8

Q 4 - Evaluate the expression 15 + 150 ÷ 52

A - 12

B - 15

C - 18

D - 21

Answer : D

Explanation

Step 1:

Simplifying exponent

15 + 150 ÷ 52 = 15 + 150 ÷ 25

Step 2:

Doing division

15 + 150 ÷ 25 = 15 + 6

Step 3:

Doing addition

15 + 6 = 21

Step 4:

So 15 + 150 ÷ 52 = 21

Q 5 - Evaluate the expression (25 − 12)3 ÷ 13

A - 121

B - 147

C - 169

D - 176

Answer : C

Explanation

Step 1:

Simplifying the parantheses

(25 − 12)3 ÷ 13 = (13)3 ÷ 13

Step 2:

Simplifying exponents

(13)3 ÷ 13 = 2197 ÷ 13

Step 3:

Doing division

2197 ÷ 13 = 169

Step 4:

So (25 − 12)3 ÷ 13 = 169

Q 6 - Evaluate the expression 11 + 54 ÷ 32

A - 15

B - 17

C - 19

D - 21

Answer : B

Explanation

Step 1:

Simplifying exponents

11 + 54 ÷ 32 = 11 + 54 ÷ 9

Step 2:

Doing division

11 + 54 ÷ 9 = 11 + 6

Step 3:

Doing addition

11 + 6 = 17

Step 4:

So 11 + 54 ÷ 32 = 17

Q 7 - Evaluate the expression (5 + 1)2 ÷ 9

A - 4

B - 5
