9514 1404 393
Answer:
a) 7
b) 20
c) 14
d) 24
Step-by-step explanation:
The desired number is found by subtracting the given number from the square of the integer just higher than the root of the given number.
a) √42 ≈ 6.5, so the desired number is 7² -42 = 49 -42 = 7
__
b) √101 ≈ 10.05, so the desired number is 11² -101 = 121 -101 = 20
__
c) √470 ≈ 21.7, so the desired number is 22² -470 = 484 -470 = 14
__
d) √1000 ≈ 31.6, so the desired number is 32² -1000 = 1024 -1000 = 24
