first let x approach 45 from below: tanx <1 and tan2x→+∞,therefore left hand side limit is zero.
x approaches 45 from above: tanx >1 and tan2x→ -∞, therefore right hand side limit is zero
Therefore the answer is that the limit is zero.

lt. (tanx)^tan2x
x->45
= e^lt. (tan2x)(tanx-1)
x->45
now calculate the limit of lt. (tan2x)(tanx-1)
x->45
it is equals to (-1)
ans. is e^-1=1/e
