expand (9-e)^3

Solution

expand

(9 - e)^{3}

Solution

729 - 243 e + 27 e^{2} - e^{3}

+1

Decimal Notation

247.87649 \dots

Solution steps

(9 - e)^{3}

Apply Perfect Cube Formula:

(a - b)^{3} = a^{3} - 3 a^{2} b + 3 a b^{2} - b^{3}

a = 9, b = e

= 9^{3} - 3 \cdot 9^{2} e + 3 \cdot 9 e^{2} - e^{3}

Simplify

9^{3} - 3 \cdot 9^{2} e + 3 \cdot 9 e^{2} - e^{3} : 729 - 243 e + 27 e^{2} - e^{3}

= 729 - 243 e + 27 e^{2} - e^{3}
