Questions and Answers

Q 1 - Evaluate the following expression with one operation and an exponent

2 × u3, u = 2

A - 14

B - 15

C - 16

D - 17

Answer : C

Explanation

Step 1:

Given u = 2

2 × u3 = 2 × 23 = 2 × 8 = 16

Step 2:

So, for u = 2, 2 × u3 = 16

Q 2 - Evaluate the following expression with one operation and an exponent

p + 23, p = 5

A - 12

B - 13

C - 14

D - 15

Answer : B

Explanation

Step 1:

Given p = 5

p + 23 = 5 + 23 = 5 + 8 = 13

Step 2:

For p = 5, p + 23 = 13

Q 3 - Evaluate the following expression with one operation and an exponent

p − 50; p = 9,

A - 8

B - 9

C - 10

D - 12

Answer : A

Explanation

Step 1:

Given p = 9

p − 50 = 9 – 1 = 8 (as 50 = 1)

Step 2:

So for p = 9, p − 50 = 8

Q 4 - Evaluate the following expression with one operation and an exponent

x3 ÷ 16, x = 4

A - 1

B - 2

C - 3

D - 4

Answer : D

Explanation

Step 1:

Given x = 4

x3 ÷ 16 = 43 ÷ 16 = 64 ÷ 16 = 4

Step 2:

So, for x = 4, x3 ÷ 16 = 4

Q 5 - Evaluate the following expression with one operation and an exponent

c + 72, c = 6

A - 52

B - 55

C - 56

D - 58

Answer : B

Explanation

Step 1:

Given c = 6

c +72 = 6 + 49 = 55

Step 2:

So, for c = 6, c +72 = 55

Q 6 - Evaluate the following expression with one operation and an exponent

m4 + 5; m = 3

A - 83

B - 85

C - 86

D - 87

Answer : C

Explanation

Step 1:

Given m = 3

m4 + 5 = 34 + 5 = 81 + 5 = 86

Step 2:

So, for m = 3, m4 + 5 = 86

Q 7 - Evaluate the following expression with one operation and an exponent

s2 + 4; s = 3

A - 10

B - 11

C - 12

D - 13

Answer : D

Explanation

Step 1:

Given s = 3

s2 + 4 = 32 + 4 = 9 + 4 = 13

Step 2:

So, for s = 3, s2 + 4 = 13

Q 8 - Evaluate the following expression with one operation and an exponent

a3 − 5, a = 4

A - 59

B - 60

C - 61

D - 62

Answer : A

Explanation

Step 1:

Given a = 4

a3 – 5 = 43 – 5 = 64 – 5 = 59

Step 2:

So, for a = 4, a3 – 5 = 59

Q 9 - Evaluate the following expression with one operation and an exponent

s2 ÷ 9; s = 6

A - 2

B - 3

C - 4

D - 5

Answer : C

Explanation

Step 1:

Given s = 6

s2 ÷ 9 = 62 ÷ 9 = 36 ÷ 9 = 4

Step 2:

So, for s = 6, s2 ÷ 9 = 4

Q 10 - Evaluate the following expression with one operation and an exponent

j − 52; j = 45

A - 15

B - 25

C - 35

D - 20

Answer : D

Explanation

Step 1:

Given j = 45

j − 52 = 45 – 25 = 20

Step 2:

So, for j = 45, j − 52 = 20
