calc((1+e)^2) — step-by-step solution

Let's evaluate:

{(1 + e)}^{2}

(1 + e) \times (1 + e)

1 \times 1

+ 1 \times e

+ e \times 1

+ e \times e

1

+ e

+ e

+ e^{2}

1 + 2 e + e^{2}

e^{2} + 2 e + 1

The approximate value of:

e^{2} + 2 e + 1

is:

{\approx 2.7183}^{2} + 2 \times \approx 2.7183 + 1

\approx 7.3891 + \approx 5.4366 + 1

\approx 12.8256 + 1

\approx 13.8256

▷Answer: $e^{2} + 2 e + 1$

▷▷Numeric value:

\approx 13.8256
