Solve [4^2+6^2+8^2+-1+20^2]

$$[ 4 ^ { 2 } + 6 ^ { 2 } + 8 ^ { 2 } + - 1 + 20 ^ { 2 } ]$$

Evaluate

$$515$$

Solution Steps

Calculate 4 to the power of 2 and get 16.

$$16+6^{2}+8^{2}-1+20^{2}$$

Calculate 6 to the power of 2 and get 36.

$$16+36+8^{2}-1+20^{2}$$

Add 16 and 36 to get 52.

$$52+8^{2}-1+20^{2}$$

Calculate 8 to the power of 2 and get 64.

$$52+64-1+20^{2}$$

Add 52 and 64 to get 116.

$$116-1+20^{2}$$

Subtract 1 from 116 to get 115.

$$115+20^{2}$$

Calculate 20 to the power of 2 and get 400.

$$115+400$$

Add 115 and 400 to get 515.

$$515$$

Factor

$$5\times 103$$
