Solution steps

(5 - 7) (5 - 7)

Apply exponent rule:

aa = a^{2}

(5 - 7) (5 - 7) = (5 - 7)^{2}

= (5 - 7)^{2}

Apply Perfect Square Formula:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

(5 - 7)^{2} = (5)^{2} - 25 \cdot 7 + 7^{2}

= (5)^{2} - 25 \cdot 7 + 7^{2}

(5)^{2} - 25 \cdot 7 + 7^{2} = 54 - 145

= 54 - 145

\frac{a ^{2}}{b ^{2}}

(- 75)^{3}

e^{- a t}
