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

2 × u^{3}, u = 2

### Answer : C

### Explanation

**Step 1:**

Given u = 2

2 × u^{3} = 2 × 2^{3} = 2 × 8 = 16

**Step 2:**

So, for u = 2, 2 × u^{3} = 16

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

p + 2^{3}, p = 5

### Answer : B

### Explanation

**Step 1:**

Given p = 5

p + 2^{3} = 5 + 2^{3} = 5 + 8 = 13

**Step 2:**

For p = 5, p + 2^{3} = 13

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

p − 5^{0}; p = 9,

### Answer : A

### Explanation

**Step 1:**

Given p = 9

p − 5^{0} = 9 – 1 = 8 (as 5^{0} = 1)

**Step 2:**

So for p = 9, p − 5^{0} = 8

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

x^{3} ÷ 16, x = 4

### Answer : D

### Explanation

**Step 1:**

Given x = 4

x^{3} ÷ 16 = 4^{3} ÷ 16 = 64 ÷ 16 = 4

**Step 2:**

So, for x = 4, x^{3} ÷ 16 = 4

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

c + 7^{2}, c = 6

### Answer : B

### Explanation

**Step 1:**

Given c = 6

c +7^{2} = 6 + 49 = 55

**Step 2:**

So, for c = 6, c +7^{2} = 55

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

m^{4} + 5; m = 3

### Answer : C

### Explanation

**Step 1:**

Given m = 3

m^{4} + 5 = 3^{4} + 5 = 81 + 5 = 86

**Step 2:**

So, for m = 3, m^{4} + 5 = 86

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

s^{2} + 4; s = 3

### Answer : D

### Explanation

**Step 1:**

Given s = 3

s^{2} + 4 = 3^{2} + 4 = 9 + 4 = 13

**Step 2:**

So, for s = 3, s^{2} + 4 = 13

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

a^{3} − 5, a = 4

### Answer : A

### Explanation

**Step 1:**

Given a = 4

a^{3} – 5 = 4^{3} – 5 = 64 – 5 = 59

**Step 2:**

So, for a = 4, a^{3} – 5 = 59

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

s^{2} ÷ 9; s = 6

### Answer : C

### Explanation

**Step 1:**

Given s = 6

s^{2} ÷ 9 = 6^{2} ÷ 9 = 36 ÷ 9 = 4

**Step 2:**

So, for s = 6, s^{2} ÷ 9 = 4

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

j − 5^{2}; j = 45

### Answer : D

### Explanation

**Step 1:**

Given j = 45

j − 5^{2} = 45 – 25 = 20

**Step 2:**

So, for j = 45, j − 5^{2} = 20
