Mathematical calculation 834.2 * (1 + x) (1 + x) (1 + x) (1 + x) (1 + x) * (1 + x) (1 + x) (1 + x) = 7875, find out what x is equal to?

Mathematical calculation 834.2 * (1 + x) (1 + x) (1 + x) (1 + x) (1 + x) * (1 + x) (1 + x) (1 + x) = 7875, find out what x is equal to?

834.2*（1+x）（1+x）（1+x）（1+x）（1+x）*（1+x）（1+x）（1+x）=7875
It can be transformed into (1 + x) ^ 8 = 7875 / 834.2 ≈ 9.448 √ 9.44 ≈ 1.324
1 + X ≈± 1.324, so x ≈ 0.324 or X ≈ 2.324

X Λ - 2 = 0.01, then how to calculate x? And: 1 Λ 5 / 6

If x Λ - 2 = 0.01, the reciprocal of the square of X is 0.01, then you can find the reciprocal first and then open it up. The answer is ± 10
The base number of 1 Λ 5 / 6 is 1. You don't care what the index is. I haven't heard of that joke. One child calculated the 100th power of three pieces of scribble paper 1 in the exam. The teacher asked everyone to change 100 to 10000 when he calculated 98 times

Problem 12: calculation - 1 + 2 + - 3 + 4-5 + 6... - 2001 + 2002 + - 2003 + 2004 =? Finally equal to solving
Don't mistake the sign, especially the minus sign

The process is as follows
The original formula = (- 1 + 2) + (- 3 + 4) + (- 5 + 6) +（-2001+2002）+（-2003+2004）
=1+1+1+…… +1 + 1 (1002 ones)
=1002
