3² × 4³ = 12^5 is False .
Reason :
LHS = 3² × 4³
= 3² × 4² × 4
= ( 3 × 4 )² × 4
= ( 12 )² × 4---( 1 )
RHS = 12^5 ---( 2 )
from ( 1 ) and ( 2 ) ,
LHS ≠ RHS

To proof : 3² * 4³ = 12
Checking :
Left Hand Side → 3² * 4³
Right Hand Side → 12
Solving Left hand side : →
→ 3² × 4³
→ ( 3 × 3 ) × ( 4 × 4 × 4 )
→ 9 × 64
→576 or 24²
Solving Right hand side : →
→ 12
→ 12 × 12 × 12 × 12 × 12
→ 248832 or 12
On Comparing RHS and LHS , we get { 576 ≠ 248832 } or 24² ≠ 12
Therefore, given statement is false.
