$(e^{\frac{9}{8}} + e^{\frac{2 \cdot 3}{2 \cdot 4}} + e^{\frac{3}{8}} \cdot 1 - 1 e^{\frac{3}{4}} - 1 e^{\frac{3}{8}} - 1 \cdot 1) \frac{8}{9}$

Step 12.11.2.4.2.2

Cancel the common factor.

$(e^{\frac{9}{8}} + e^{\frac{2 \cdot 3}{2 \cdot 4}} + e^{\frac{3}{8}} \cdot 1 - 1 e^{\frac{3}{4}} - 1 e^{\frac{3}{8}} - 1 \cdot 1) \frac{8}{9}$

Step 12.11.2.4.2.3

Rewrite the expression.

$(e^{\frac{9}{8}} + e^{\frac{3}{4}} + e^{\frac{3}{8}} \cdot 1 - 1 e^{\frac{3}{4}} - 1 e^{\frac{3}{8}} - 1 \cdot 1) \frac{8}{9}$

Step 12.11.3

Multiply $e^{\frac{3}{8}}$ by $1$ .

$(e^{\frac{9}{8}} + e^{\frac{3}{4}} + e^{\frac{3}{8}} - 1 e^{\frac{3}{4}} - 1 e^{\frac{3}{8}} - 1 \cdot 1) \frac{8}{9}$

Step 12.11.4

Rewrite $- 1 e^{\frac{3}{4}}$ as $- e^{\frac{3}{4}}$ .

$(e^{\frac{9}{8}} + e^{\frac{3}{4}} + e^{\frac{3}{8}} - e^{\frac{3}{4}} - 1 e^{\frac{3}{8}} - 1 \cdot 1) \frac{8}{9}$

Step 12.11.5

Rewrite $- 1 e^{\frac{3}{8}}$ as $- e^{\frac{3}{8}}$ .

$(e^{\frac{9}{8}} + e^{\frac{3}{4}} + e^{\frac{3}{8}} - e^{\frac{3}{4}} - e^{\frac{3}{8}} - 1 \cdot 1) \frac{8}{9}$

Step 12.11.6

Multiply $- 1$ by $1$ .

$(e^{\frac{9}{8}} + e^{\frac{3}{4}} + e^{\frac{3}{8}} - e^{\frac{3}{4}} - e^{\frac{3}{8}} - 1) \frac{8}{9}$

Step 12.12

Subtract $e^{\frac{3}{4}}$ from $e^{\frac{3}{4}}$ .

$(e^{\frac{9}{8}} + 0 + e^{\frac{3}{8}} - e^{\frac{3}{8}} - 1) \frac{8}{9}$

Step 12.13

Add $e^{\frac{9}{8}}$ and $0$ .

$(e^{\frac{9}{8}} + e^{\frac{3}{8}} - e^{\frac{3}{8}} - 1) \frac{8}{9}$

Step 12.14

Subtract $e^{\frac{3}{8}}$ from $e^{\frac{3}{8}}$ .

$(e^{\frac{9}{8}} + 0 - 1) \frac{8}{9}$

Step 12.15

Add $e^{\frac{9}{8}}$ and $0$ .

$(e^{\frac{9}{8}} - 1) \frac{8}{9}$

Step 12.16

Apply the distributive property.

$e^{\frac{9}{8}} \frac{8}{9} - 1 (\frac{8}{9})$

Step 12.17

Combine $e^{\frac{9}{8}}$ and $\frac{8}{9}$ .

$\frac{e^{\frac{9}{8}} \cdot 8}{9} - 1 (\frac{8}{9})$

Step 12.18

Rewrite $- 1 (\frac{8}{9})$ as $- (\frac{8}{9})$ .

$\frac{e^{\frac{9}{8}} \cdot 8}{9} - (\frac{8}{9})$

Step 12.19

Move $8$ to the left of $e^{\frac{9}{8}}$ .

$\frac{8 e^{\frac{9}{8}}}{9} - \frac{8}{9}$

Step 13

The result can be shown in multiple forms.

Exact Form:

$\frac{8 e^{\frac{9}{8}}}{9} - \frac{8}{9}$

Decimal Form:

$1.84908164 \dots$
