Solution Steps

Multiply 5 and 24 to get 120. Multiply 3 and 7 to get 21. Multiply 5 and 8 to get 40. Multiply 25 and 8 to get 200. Multiply 5 and 4 to get 20. Multiply 38 and 2 to get 76.

$$21.5\times 3+120+21\times 4+40\times 4+4^{2}+200\times 1.3+150+20\times 20+76+150$$

Multiply 21.5 and 3 to get 64.5.

$$64.5+120+21\times 4+40\times 4+4^{2}+200\times 1.3+150+20\times 20+76+150$$

Add 64.5 and 120 to get 184.5.

$$184.5+21\times 4+40\times 4+4^{2}+200\times 1.3+150+20\times 20+76+150$$

Multiply 21 and 4 to get 84.

$$184.5+84+40\times 4+4^{2}+200\times 1.3+150+20\times 20+76+150$$

Add 184.5 and 84 to get 268.5.

$$268.5+40\times 4+4^{2}+200\times 1.3+150+20\times 20+76+150$$

Multiply 40 and 4 to get 160.

$$268.5+160+4^{2}+200\times 1.3+150+20\times 20+76+150$$

Add 268.5 and 160 to get 428.5.

$$428.5+4^{2}+200\times 1.3+150+20\times 20+76+150$$

Calculate 4 to the power of 2 and get 16.

$$428.5+16+200\times 1.3+150+20\times 20+76+150$$

Add 428.5 and 16 to get 444.5.

$$444.5+200\times 1.3+150+20\times 20+76+150$$

Multiply 200 and 1.3 to get 260.

$$444.5+260+150+20\times 20+76+150$$

Add 444.5 and 260 to get 704.5.

$$704.5+150+20\times 20+76+150$$

Add 704.5 and 150 to get 854.5.

$$854.5+20\times 20+76+150$$

Multiply 20 and 20 to get 400.

$$854.5+400+76+150$$

Add 854.5 and 400 to get 1254.5.

$$1254.5+76+150$$

Add 1254.5 and 76 to get 1330.5.

$$1330.5+150$$

Add 1330.5 and 150 to get 1480.5.

$$1480.5$$

Factor

$$\frac{7 \cdot 47 \cdot 3 ^ {2}}{2} = 1480\frac{1}{2} = 1480.5$$
