Verified Answer
Evaluate the exponential expression(−b)4× (−b)5,for ...
(-b)4= (-44) =(-4 × -4) × (-4 × -4)
=16×16 (as -×-=+) =256
(-b)5=1024
so, -1024 × 256 = -262144

Evaluate the exponential expression(−b)4× (−b)5,for ...
When (−b)4 × (−b)5 and b= 4 , (−4)4 × (−4)5
= (−4) raised to the power 9
= −4×−4×−4×−4×−4×−4×−4×−4×−4=−262,144
= (−4) raised to the power 9
= −4×−4×−4×−4×−4×−4×−4×−4×−4=−262,144
