Using the laws of indices , 4⁵ ÷ 4² can rewritten as 4³.
<h3>What is the result of the division in exponent form?</h3>
Given the expression; 4⁵ ÷ 4²
To perform the division operation, we use one of the laws of indices;
Given that;
Now, we apply the laws of indices ;
4⁵ ÷ 4² = 4⁵⁻² = 4³
Therefore, using the laws of indices, 4⁵ ÷ 4² can rewritten as 4³.

Step-by-step explanation:
Answer:
57.78 km/hr
Step-by-step explanation:
Total time taken, t = 6 hours
Total distance covered, d = 520 km
Distance by car = 260
Distance by train = 520 - 260 = 260 km
Train speed = x
Car speed = 2x
Average speed speed = 3x /2
Speed = distance / time
1.5x = 520 / 6
9x = 520
x = 520 / 9
x = 57.777
Average speed of train = 57.78 km/hr
Add whole numbers: 2 + 6 + 8 = 16
Add fractions:
= 1/3 + 3/4 + 1/2
= (8 + 18 + 12) ÷ 24
= 38/24 or 1 14/24 or simplified to 1 7/12
Total surface area = 16 + 1 7/12 or 17 7/12
