The length of a certain bacterium is about 0.0000018 meters. Please use scientific counting method to express the length of this bacterium in nanometers. (one nanometer = 10 to the - 9th power) fast

The length of a certain bacterium is about 0.0000018 meters. Please use scientific counting method to express the length of this bacterium in nanometers. (one nanometer = 10 to the - 9th power) fast


0.0000018m = 1.8x10-710; - 6M
It is known that 1nm = 10 & # 710; - 9m, 1.8x10 & # 710; - 6m = 1.8x10 & # 710; 3nm = 1800 nm



The diameter is 0.0000057. How many meters is scientific notation equal to


0.0000057 scientific notation is equal to 5.7x (the negative sixth power of 10)



The diameter of silver atom is 0.0003 micron, which is equivalent to______ Meters (in scientific notation, 1 micron = 10-6 meters)


000 3 × 10-6 = 3 × 10-10, so the answer is: 3 × 10-10



Given z = x + iy, what is the modulus of the square of the Z power of E


Given that the modulus of complex Z is equal to 1, find the maximum value of the modulus of (z-square-z + 1)
Z & # 178; - Z + 1 = (z-0.5) & # 178; + 0.75 from - 1 ≤ Z ≤ 1 to - 3 / 2 ≤ z-0.5 ≤ 1 / 2, so 1 / 4 ≤ (z-0.5) & # 178; ≤ 9 / 4, so 1 ≤ (z-0.5) & # 178; + 0.75 ≤ 3, that is, the maximum value of the module of (Z-Z + 1) is 3, and the minimum value is 1
I guess



What is the n power of I + the - n power of I


i¹=i i²=-1 i³=-i i⁴=1
I ^ 5 = I start the cycle, once every 4 cycles
therefore
When n = 4K (k is a natural number), I & # 8319; = 1, I - # 8319; = 1, then the original formula = 1 + 1 = 2
When n = 4K + 1 (k is a natural number), I & # 8319; = I - # 8319; = 1 / I = - I, then the original formula = I-I = 0
When n = 4K + 2 (k is a natural number), I & # 8319; = - 1, I - &# 8319; = 1 / I = - 1, then the original formula = - 1-1 = - 2
When n = 4K + 3 (k is a natural number), I & # 8319; = - I - # 8319; = 1 / - I = I, then the original formula = - I + I = 0
To sum up
I &; + I - &; = 2 or 0 or - 2



How much is the negative quarter to 4025 times 16 to 2013?
Look up there,


(-1/4)^4025*16^2013
=(-1/4)^4025*(4^2)^2013
=(-/4)^4025*4^4026
=[(-1/4)*4]^4025*4
=-1*4
=-4



What is the negative quarter power of 0.0081?


0081 = 1 / 0.3 = 10 / 3



2 × (- 1 / 2) to the third power - 3 × (- 1 / 2) to the second power + 3 × (- 1 / 2) - 1 =? 28-2 × 3 to the second power - (- 2 × 3) to the second power =?


2 × (- 1 / 2) - 3 × (- 1 / 2) - 1 = 2 × (- 1 / 8) - 3 × (1 / 4) + 3 × (- 1 / 2) - 1 = - 1 / 4-3-2-1 = - 7 / 2
The second power of 28-2 × 3 - (- 2 × 3) is 28-2 × 9 - (- 6) = 28-18 + 6 = 16
