Evaluate

$$578$$

Solution Steps

Add 4 and 5 to get 9.

$$10\left(9+4\right)-5\times 8+\left(10+4+8+6+6+4+10+4+5+4\right)\times 8$$

Add 9 and 4 to get 13.

$$10\times 13-5\times 8+\left(10+4+8+6+6+4+10+4+5+4\right)\times 8$$

Multiply 10 and 13 to get 130.

$$130-5\times 8+\left(10+4+8+6+6+4+10+4+5+4\right)\times 8$$

Multiply 5 and 8 to get 40.

$$130-40+\left(10+4+8+6+6+4+10+4+5+4\right)\times 8$$

Subtract 40 from 130 to get 90.

$$90+\left(10+4+8+6+6+4+10+4+5+4\right)\times 8$$

Add 10 and 4 to get 14.

$$90+\left(14+8+6+6+4+10+4+5+4\right)\times 8$$

Add 14 and 8 to get 22.

$$90+\left(22+6+6+4+10+4+5+4\right)\times 8$$

Add 22 and 6 to get 28.

$$90+\left(28+6+4+10+4+5+4\right)\times 8$$

Add 28 and 6 to get 34.

$$90+\left(34+4+10+4+5+4\right)\times 8$$

Add 34 and 4 to get 38.

$$90+\left(38+10+4+5+4\right)\times 8$$

Add 38 and 10 to get 48.

$$90+\left(48+4+5+4\right)\times 8$$

Add 48 and 4 to get 52.

$$90+\left(52+5+4\right)\times 8$$

Add 52 and 5 to get 57.

$$90+\left(57+4\right)\times 8$$

Add 57 and 4 to get 61.

$$90+61\times 8$$

Multiply 61 and 8 to get 488.

$$90+488$$

Add 90 and 488 to get 578.

$$578$$

Factor

$$2\times 17^{2}$$
