For q1 and q2 I have given explanation already.
q3 to multiply radicals the index must be same.
option a . different index. ∛5 √2
option b . same index so √3 √2 = √6
option c. again different index.
What’s the question? Maybe then I can help.
1.50 pounds.

Answer:
Scuba diver started at 2 feet above the sea level, dove down 20 feet, and rose up 8 feet
Step-by-step explanation:
The initial number is 2 which is more than 0 that means the diver did not start at a ground level but above than that.
The negative 20 denotes that he went down the sea level, to the extent of the number provided in feet.
Further, after that dive the positive number provides the height in feet covered to rise up from the down level of dive.
