Explanation

Given:

A = positive even integer (2,4,6...)

B = positive even integer (2,4,6...)

Check both:

1) (-2A)^B

Base is -2A = negative

Power B = even

Negative ^ Even = Positive

So (-2A)^B = +(2A)^B = Positive number

2) -2A²B

= -2 x A² x B

= Negative number

Positive is always greater than Negative.

So (-2A)^B is greatest.

Clock strikes:

1 o'clock = 1 strike

2 o'clock = 2 strikes

...

12 o'clock = 12 strikes

Total in 12 hours = 1+2+3+4+5+6+7+8+9+10+11+12

This is sum of first 12 numbers.

Formula = n(n+1)/2

= 12 x 13 / 2

= 156 / 2

= 78
