Expression a, b and c are shown below a. b. c 20^2-18^2. 8(4^2)+2^4. 15^2-3^4 which expression or expressions have the same value as 12^2

We know that
12²> (2²*3)²> 16*9> 144

20²-18²> (2²*5)²-(2*3²)²> 16*25-4*81> 400-324> 76

8(4^2)+2^4> 2³*(4²)+2²*2²> 2³*(2²*2²)+2²*2²> 128+16> 144

15²-3^4> (3*5)²-(3²*3²)> 9*25-9*9> 225-81> 144

the answers are
8(4^2)+2^4.
15^2-3^4

The clear answer is clearly 25 is very clear to me
