(1) The fourth power of (- 2x to the fourth power) + the tenth power of 2x times the third power of (- 2x to the second power) + the fourth power of 2x times 5 times the third power of (x to the fourth power)
(2) (x-y-5) (x + Y-5) (3) use the multiplication formula to calculate: the 2nd power of 1005 (4) (- the 3rd power of the 2nd power n of 1 / 2-The 2nd power of the 3rd power n of 1 / 4-The 2nd power of the 3rd power n of 1 / 4-The 6th power of 1 / 6) divided by (- 1 / 12) - 3M (the square of 2n + Mn)
It's also a detailed formula. Thank you

(1) (- 2x to the 4th power) + 2x to the 10th power multiplied by (- 2x to the 2nd power) + 2x to the 4th power multiplied by 5 times (x to the 4th power) = 16x ^ 16-16x ^ 16 + 2x ^ 4 * 5 * x ^ 12 = 10x ^ 16 (2) (x-y-5) (x + Y-5) = x & # 178; - 10x + 25-y & # 178; 3) calculate by multiplication formula: 1005 to the 2nd power
