Question 1
1 / -0

3125= 5-

A
8

B
7

C
6

D
5

Solution

The factors of 3125 = 5 × 5 × 5 × 5 × 5

So it can be expressed in the exponential form as 5⁵.
Question 2
1 / -0

5⁴= ____

A
1025

B
525

C
125

D
625

Solution

The above value can be written as,

= 5 × 5 × 5 × 5

= 625
Question 3
1 / -0

b × b × b × b= b^__

A
1

B
2

C
3

D
4

Solution

The given question can be expressed in the exponential form as b⁴.
Question 4
1 / -0

2 × 2 × a × a= 2² ×a^---

A
4

B
3

C
2

D
1

Solution

The given question can be expressed in the exponential form as 2² × a².
Question 5
1 / -0

6 × 6 × 6 × 6= (6)^_

A
2

B
3

C
4

D
5

Solution

The given question can be expressed in the exponential form as 6⁴.
Question 6
1 / -0

2⁶ __ 8²

A
<

B
>

C
=

D
can not determine

Solution

The expansion of 2⁶ = 2 × 2 × 2 × 2 × 2 × 2 = 64

The expansion of 8² = 8 × 8= 64

Clearly,

256 = 64

So, 2⁶= 8²
Question 7
1 / -0

6¹⁵ ÷ 6¹⁰= 6^---

A
2

B
3

C
4

D
5

Solution

6¹⁵ ÷ 6¹⁰= 6^---

By the rule of dividing the powers with same base = a^m÷ aⁿ = a^{m – n}

Then,

= (6)^{15 – 10}

= 6⁵
Question 8
1 / -0

540= ___

A
2²×3³ ×5

B
2×3³ ×5

C
2²×3 ×5

D
2²×3³

Solution

Factors of 540 = 2 × 2 × 3 × 3 × 3 × 5

= 2²× 3³ × 5
Question 9
1 / -0

5³ __ 3⁵

A
>

B
<

C
=

D
can not determine

Solution

The expansion of 5³ = 5 × 5 × 5 = 125

The expansion of 3⁵ = 3 × 3 × 3 × 3 × 3= 243

Clearly,

125 < 243

So, 5³ < 3⁵
Question 10
1 / -0

2.7 × 10¹² __ 1.5 × 10⁸

A
<

B
>

C
=

D
can not determine

Solution

By observing the question

Comparing the exponents of base 10,

Clearly,

2.7 × 10¹² > 1.5 × 10⁸
