Answer 1

Answer:

1. 1/1  2. 73/10000 3. (Unknown) 4. Answer is 4 5. (Unknown) 6. 961

Step-by-step explanation:

1. If you reciprocal 1/1 it will be the equal to its reciprocal

2. 0.00073 in standard form = p/q where q is not equal to 0

= 73/10000

4. As 21296 is an even number, it can be multiplied by 4 to make a perfect cube.

6. As the largest 3 digit number is 999, if you add 38 to it, it becomes a 4 digit number so you need to subtract 38 from 999 = 961

38 is the square number.
