Please help me on question #2
1 answer:
- Product Rule of Radicals: √ab = √a × √b
So firstly, factor out i (i = √-1):
10i√80
Next, apply the product rule of radicals and simplify the radical as such:
√80 = √10 × √8 = √5 × √2 × √4 × √2 = 2 × 2 × √5 = 4√5
10i × 4√5 = 40i√5
<u>Your final answer is 40i√5.</u>

Answer:
Q1. 1050 miles
Q2. 1h 30m
Step-by-step explanation:
Q1. 1h = 300 miles
3
h = 3.5 × 300 miles
= 1050 miles
Q2. 68km = 1h
102km = 
× 1h
= 1.5h
= 1h 30m
Answer:
The coefficient is 3.
Step-by-step explanation:
The coefficient is the number that is grouped with an unknown number represented by a letter.
Multiply by 1/3 to reduce.
228*1/3=76m^2
216*1/3=72m^3
Multiply by 4 to increase.
228*4=912m^2
216*4=864m^3
