Please its very urgent :( Name five whole numbers that can be expressed as the difference of two perfect squares. Show the math!
Tatiana [17]

Answer:

9, 17, 3, 1600, 11

Step-by-step explanation:

Difference of two perfect squares:

a^2-b^2=(a-b)(a+b)

It seems that you want some

x=a^2-b^2, x \in \mathbb{Z}_{\ge 0}

Note: there's no official symbol for the set of whole numbers, I've already seem \mathbb{W}, \mathbb{Z}^+, as well.

5^2-4^2=25-16=9

There are infinitely many numbers that can satisfy the condition given.

The only condition is that a\geq b, once we are considering whole numbers and not integers.

x_{1}=5^2-4^2=25-16=9

x_{2}=9^2-8^2=81-64=17

x_{3}=2^2-1^2=4-1=3

x_{4}=50^2-30^2=2500-900=1600

x_{5}=6^2-5^2=36-25=11

  • By representing radicals as numbers with rational exponents, the properties of rational exponents can be used to simplify statements containing radicals or rational exponents. This allows you to apply the same rational exponent qualities to them.

Hello there are two questions in the link's if both were solved that would be awesome.
Stels [109]

Answer:

\frac{x^{\frac{5}{6}} }{x^{\frac{1}{6}} } = x^{(\frac{5}{6} -\frac{1}{6}) }=  x^{\frac{4}{6} }\\\sqrt{x} . \sqrt[4]{x} = x^{\frac{1}{2} } . x^{\frac{1}{4} } = x^{(\frac{1}{2} +\frac{1}{4}) } = x^{\frac{3}{4}
