Answer 1

Answer:

Correct option is:

9 ⋅ 104 is 3 times larger than 3 ⋅ 102

Step-by-step explanation:

9 ⋅ 104 = 3×3×104

3 ⋅ 102 = 3×102

104 is near to 102

Let 104 ≈ 102

3×104 ≈ 3×102

3×3×104 ≈ 3×3×102 = 3(3×102)

i.e. 9 · 104 ≈ 3(3 · 102)

Hence, Correct option is:

9 ⋅ 104 is 3 times larger than 3 ⋅ 102
