simplify e^{9xy}*e^{-9xy}

Solution

simplify

e^{9 x y} \cdot e^{- 9 x y}

Solution

1

Solution steps

e^{9 x y} e^{- 9 x y}

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

e^{9 x y} e^{- 9 x y} = e^{9 x y - 9 x y}

= e^{9 x y - 9 x y}

Add similar elements:

9 x y - 9 x y = 0

= e^{0}

Apply rule

a^{0} = 1, a \neq = 0

= 1
