Answer:
2/√10 - 8√2
Step-by-step explanation:
Multiply the numerator and denominator by a root to remove the radical from the numerator.
The number of new calculators tested was 50 . . . 8 were bad and 42 were good.
The ratio of defective ones to new ones tested is 8:50 or 4:25 or 16% .
To solve the problem find the value of (45)^2 at first
The answer is 25 with the remainder 75
You can simplify the fraction to be 25/26
