Answer:
The greatest number is A. 1.3 * 10⁵
Explanation:
Let's find the greatest number:
Option A : 1.3 * 10⁵ = 1.3 * 100,000 = 130,000
Option B : 9.8 * 10² = 9.8 * 100 = 980
Option C : 9.6 * 10⁴ = 9.6 * 10,000 = 96,000
Option D : 4.6 * 10⁻⁵ = 4.6 * 0.00001 = 0.000046
130,000 > 96,000 > 980 > 0.000046
The greatest number is A. 1.3 * 10⁵
