Correct Answer: 25
Explanation:
√4375 / √7 = √4375 / 7
= √625
= 25
Correct Answer: 25
Explanation:
Let 250 / √x = 10.
Then √x= 250 / 10 = 25
∴ x = 625
Correct Answer: 16
Explanation:
Let √x / 200 = 0.02
Then, √x = 200 x 0.02 = 4.
So, x = 16
Correct Answer: 5?6
Explanation:
?10 x ?15
= ?10 x 15
= ?150
= ?25 x 6
= ?25 x ?6
= 5?6

Explanation:
?8/3 =?24/9
= ?24/3
= 4.899/3
=1.633
Correct Answer: 825
Explanation:
Let N / √2.25 = 550.
Then, N / 1.5 = 550
∴ N = (550 x 1.5)
= (550 x 15) /10
= 825
Correct Answer: .6241
Explanation:
75.24 + N = 8.71 x 8.71
? N = 75.8641 - 75.24
? N = .6241
