99(Square of 10+1)(4th power of 10+1)+1
Just now it was (-1/8)^5×2^11
=-(2^-3)^5×2^11
=-2^(-15)×2^11
=-2^(-15+11)
=-2^(-4)
=-1/16
Missing a minus sign.
99(Square of 10+1)(4th power of 10+1)+1
=(10^2-1)(10^2+1)(10^4+1)+1
=(10^4-1)(10^4+1)+1
=10^8-1+1
=10^8
Using the square difference formula to calculate:100 of the second power minus 99 of the second power plus 98 of the second power minus 97 of the second power plus 2 of the second power minus 1 of the second power
(100X100-99x99)+(98x98-97x97)+...... +(2X2-1x1)
=(100+99)+(98+97)+…… +(2+1)
=100+99+98+91+…… +2+1
=5050
(100X100-99x99)+(98x98-97x97)+... +(2X2-1x1)
=(100+99)+(98+97)+…… +(2+1)
=100+99+98+91+…… +2+1
=5050

The set of solutions of absolute value inequality x whose absolute value is less than or equal to (a is greater than or equal to 0) can be obtained as follows: the geometric meaning of the absolute value of x whose absolute value is less than or equal to a on the number axis is "the distance to the origin is not more than a ", so its solution set is -a greater than or equal to x less than or equal to a. According to the above, the following inequality can be solved:(1) the absolute value of x is less than or equal to 3(2) the absolute value of 2x-1 is less than or equal to 5 The set of solutions of absolute value inequality x whose absolute value is less than or equal to (a is greater than or equal to 0) can be obtained as follows: the geometric meaning of the absolute value of x whose absolute value is less than or equal to a on the number axis is that the distance to the origin is not more than a, so its solution set is that -a is greater than or equal to x whose absolute value is less than or equal to a.
