70 μ M = (in scientific notation)

=7*10^(-5)
=Multiply by - 7 meters

Turn 30 microns into meters (in scientific notation)
There's another one, 14785 to the thousandth

30 μ M = 3 × 10-5 power
The exact number of 14785 is 15000
Believe me, it must be right

The diameter of red blood cells is about 7.5 microns. 1. What is the diameter of red blood cells? (expressed by scientific notation)
There are about 5 million red blood cells in 2.1 cubic millimeter blood. If these red blood cells are arranged in a long string, how many meters is its length?

1 μ M = 10 ^ - 6 m (- 6 th power)
7.5 μ M = 7.5x10 (- 6 th) M
If these red blood cells are arranged in a long string, how many meters is their length?
7.5 x (to the - 6th power of 10) x 5 x 10 ^ 6 = 37.5m

Find the remainder of X 128 power + X 110 power - x 32 power + x 8 power + x 2 power - x divided by X-1

[x^128+x^110-x^32+x^8+x^2-x]/[x-1]
=[x^127+x^126+...x^110+2(x^109+...+x^32)+x^31+...+x^8+2(x^7+...x^2)+3x].2x
The remainder is: 2x

If 2x + 5y-3 = 0, try to find the x power of 4 and the Y power of X32?
To step can be slightly clothing point! Right + 30 points!

X power of 4, y power of X32
=4^x*32^y
=2^2x*2^5y
=2^(2x+5y)
=2^3
=8

Calculate 1 / 1-x + 1 / 1 + X + 2 / 1 + x2 + 4 / 1 + X4 + 8 / 1 + X8 +... + 2 ^ n / 1 + x ^ 2n

1 / 1-x + 1 / 1 + x = 2 / 1-x2 2 / 1-x2 + 2 / 1 + x2 = 4 / 1-x4 -------- you can see where to add, the result is to replace the addition of the denominator of the next number with subtraction. Therefore, the result is 2 ^ (n + 1) / 1-x ^ 2 (n + 1)

Simplified evaluation: (x + 1) (x2 + 1) (x4 + 1) (x8 + 1) where x = 2

: (x + 1) (x ^ 2 + 1) (x ^ 4 + 1) (x ^ 8 + 1) where x = 2 (x-1) = 1: (x-1) (x + 1) (x ^ 2 + 1) (x ^ 4 + 1) (x ^ 8 + 1) = (x ^ 2-1)) (x ^ 2 + 1) (x ^ 4 + 1) (x ^ 8 + 1) = (x ^ 4-1)) (x ^ 4 + 1) (x ^ 8 + 1) = (x ^ 8-1) (x ^ 8 + 1) = x ^ 16-1 = 2 ^ 16-1

How to do (x + 1) (x2 + 1) (x4 + 1) (x8 + 1), I want to solve the problem
X2 is the square of X

Multiply by (x-1) and divide by (x-1)
(x+1)(x-1)=x^2-1
(x^2-1)(x^2+1)=x^4-1
(x^4-1)(x^4+1)=x^8-1
(x^8-1)(x^8+1)=x^16-1
Finally, (x ^ 16-1) / X-1

(x+1)(x2+1)(x4+1)(x8+1)(x16+1)
(x2 + 1) means the square of X + 1

(x+1)(x2+1)(x4+1)(x8+1)(x16+1)
=(x+1)(x-1)(x2+1)(x4+1)(x8+1)(x16+1)/(x-1)
=(x32-1)/(x-1)
=1+x+x2+x3+...+x31

When x = the second power of (x + 2) + 2009 has a minimum value, which is

When x = - 2, the second power of (x + 2) + 2009 has the minimum value, which is: 2009
