What is the value of the expression i^0 x i^1 x i^2xi^3xi^4

monitta

Answer: The answer is - 1.

Step-by-step explanation: We are given to find the value of the given expression

$E_c=i^0\times i^1\times i^2\times i^3\times i^4.$

We know that 'i' is an imaginary unit and its value is √-1. So, we have

$i^0=(\sqrt{-1})^0=1,\\\\i^1=i=\sqrt{-1},\\\\i^2=(\sqrt{-1})^2=-1,\\\\i^3=i^2.I=(-1)i=-\sqrt{-1},\\\\i^4=(i^2)^2=(-1)^2=1.$

Therefore, the given expression becomes

$E_c\\\\=i^0\times i^1\times i^2\times i^3\times i^4\\\\=1\times \sqrt{-1}\times(-1)\times({-\sqrt{-1}})\times 1\\\\=1\times (-1)\\\\=-1.$ .

Thus, the answer is - 1.

The area of a square is 160x^5y^2. What is the length of one side?

Aleksandr [31]

------------------------------------------------------------------
Formula of area of square
------------------------------------------------------------------
Area of square = Length x Length
Area of square = Length2

------------------------------------------------------------------
Given information
------------------------------------------------------------------
Area of square = $160x^5y^2$

------------------------------------------------------------------
Find length
------------------------------------------------------------------
$length^2 = 160x^5y^2$
$length = \sqrt{160x^5y^2}$
$length = 4y\sqrt{10x^5}$

-----------------------------------------------------------------
$\Longrightarrow \ Answer: \boxed {\boxed{ 4y\sqrt{10x^5} }}
$

You have learned some new ways in this module to prove that triangles are similar Please describe some of these new postulates a

Finger [1]

Answer:

TA = 6 units

GT = 10 units

Step-by-step explanation:

Angle G is common to both triangles, so that's a congruent angle.

Since RT is parallel to EA,

Angle R = Angle E

And

Angle T = Angle A

When two triangles have the same distribution of angles, they are similar (by AAA).

Therefore GRT and GEA are similar

GE/GR = GA/GT

8/5 = 16/(16-x)

16-x = 16 × 5/8

16 - x = 10

x = 16 - 10

x = 6

GT = 16 - x = 16 - 6 = 10
