Y = k/x
5 = k/8
k = 5 x 8 = 40
Therefore,
y = 40/14 = 2.86

Write an expression with a negative exponent that has a value between 0 and 1/2
aliya0001 [1]
<span>Exponent is a number used to express shorter equation; it is a number that says how many times you are going to multiply the base number.
</span><span>
Exponents have several laws, here are some:
=> x^1 = x
=> x^0 = 1
=> x^-1 = 1/x
=> x^m x^n = X^m+n
=> x^m/x^n = x^m-n

And since we were asked to write an expression with a negative exponent that has a value between 0 and ½
=> 2^ -2 = ½

Given z^3 = 3 + square root 3i which letter represents z
Marianna [84]

The expression that represents the value of z is \sqrt[3]{3 + i\sqrt 3 }

<h3>What are complex numbers?</h3>

Complex numbers are numbers that have real and imaginary parts

A complex number (n) is represented as:

n = a + bi

From the above expression, we have:

  • a represents the real part
  • bi represents the imaginary part

Given that:

z^3 = 3 + \sqrt 3 i

Rewrite the above expression as:

z^3 = 3 + i\sqrt 3

Take the cube roots of both sides

z = \sqrt[3]{3 + i\sqrt 3 }

The letters are not given.

Hence, the expression that represents the value of z is \sqrt[3]{3 + i\sqrt 3 }
