Decimal Notation

1.51668 \dots

Solution steps

(7 - 2) (7 - 2)

Apply exponent rule:

aa = a^{2}

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

= (7 - 2)^{2}

Apply Perfect Square Formula:

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

(7 - 2)^{2} = (7)^{2} - 272 + (2)^{2}

= (7)^{2} - 272 + (2)^{2}

(7)^{2} - 272 + (2)^{2} = 9 - 214

= 9 - 214

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

e^{- 3.48}

3.2 \cdot 1 0^{- 4}

e^{- 9 t} t^{5}

- 6 e^{- 0.05 (20)}
