How to calculate the minus 1.1 power of 10

How to calculate the minus 1.1 power of 10

10^(-1.1)=1/(10^1.1)
10 ^ 1.1 = 10 ^ (11 / 10) = power 10 ^ 11

How to calculate the minus 27 power of 10?

To put it bluntly, it's one tenth to the 27th power, which is 0.00000 27. There are 27 places after the decimal point

How to calculate the negative second power of 10

10 ^ - 2 = 1 / 10 ^ 2 = 1 / 100 (this is a formula, the - n power of any number is equal to the reciprocal of the nth power of this number, that is, a ^ - n = 1 / A ^ n)

1. 2, Tan α = 2, then Tan (π / 4 + α) is equal to less? I really don't understand the detailed steps

By using the factorization formula of square difference of two numbers [a ^ 2-B ^ 2 = (a + b) (a-b)], the fourth power is transformed into a quadratic power, and then simplified by trigonometric function. CIN ^ 4 α - Sin ^ 4 α = (con ^ 2 α) ^ 2 - (sin ^ 2 α) ^ 2 = (con ^ 2 α + sin ^ 2 α) (con ^ 2 α - Sin ^ 2 α) is caused by sin ^ 2 α + con ^ 2 α = 1, con ^ 2 α - Sin ^ 2

Given two-thirds of cos α, find the value of (1 + Tan, the fourth power α)?

cosα=2/3
Because sin? α + cos? α = 1
So sin? α = 5 / 9
So tan? α = sin? α / cos? α = 5 / 4
So 1 + Tan to the fourth power α = 1 + 25 / 16 = 41 / 16

What is the fourth power 270 ° of COS and 60 ° square of Tan?

The fourth power of COS is 270 ° = 0
The square of Tan is 60 ° = 3

If Tan α > 0, cos α = - 3 / 5, find the value of Tan α · cos α cubic / 1-sin α

cosa=-3/5

(4 / 3) to the 2nd power - (6.5) × 4 + (- 2) of 13 × [the 3rd power of 2 + (- 2)]

(4/3)²=19/6
6.5×4/13=13/2×4/13=2
(- 2) quartic = 16
[2 + (- 2) to the third power] = - 6
19/6-2+16/（-6）=-3/2=-1.5

2 (x-1) to the third power = 6 and 3 / 4

2 (x-1) to the third power = 6 and 3 / 4
2 (x-1) to the third power = 27 / 4
The third power of (x-1) is 27 / 8
x-1=3/2
x=5/2
