6 + 4 = 578  if 6+1=37,2+4=66,1+9=84,

Step-by-step explanation:

6+1=37,2+4=66,1+9=84,6+4=?​

6 + 1

= (6 * 1)²  + √1

= 6² + 1

= 36 + 1

= 37

2 + 4

= (2 * 4)² + √4

= 8² + 1

= 64 + 2

= 66

1 + 9

= ( 1* 9)² + √9

= 9² + 3

= 81 + 3

= 84

6 + 4

= (6 * 4)² + √4

= 24² + 2

= 576 + 2

= 578

Logic is

a + b  = c

Answer 2

The missing number is 578.

Step-by-step explanation:

Consider the provided series.

Observe the pattern.

1) Multiply both the number.

2) Square the number you obtained.

3) Add the square root of last number with the number you obtained.

6+1=37⇒ (6×1)² + √1 = 6² + 1 = 37

2+4=66⇒ (4×2)² + √4 = 8² + 2 = 66

1+9=84⇒ (1×9)² + √9 = 9² + 3 = 84

6+4=?⇒ (6×4)² + √4 = 24² + 2 = 578

Hence, the missing number is 578.
