simplify 2(e^t)(e^{-t})

Solution

simplify

2 (e^{t}) (e^{- t})

Solution

2

Solution steps

2 (e^{t}) (e^{- t})

Apply exponent rule:

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

e^{t} e^{- t} = e^{t - t}

= 2 e^{t - t}

Add similar elements:

t - t = 0

= 2 e^{0}

Apply rule

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

e^{0} = 1

= 2 \cdot 1

Multiply the numbers:

2 \cdot 1 = 2

= 2
