Assume x <span>> 0

</span>√(2x⁵/18)

= √(2/18) * √(x⁵)

= √(1/9) * √(x⁴ · x)

= 1/3 * √x⁴ * √x

= 1/3 * x² * √x

= 1/3 * x²√x

= \frac{ x^{2}  \sqrt{x} }{3}

Answer with explanation:

The Meaning of equivalent expression is those expressions, in which when you replace the variables by some constant values , in the original expression and the reduced expression,the both expression produce the same numerical value.

The expression which is equivalent to:

\rightarrow\sqrt {\frac{2x^5}{18}}\\\\=\sqrt{\frac{x^5}{9}}\\\\=\frac{x^2}{3}\times\sqrt{x}

This can be illustrated by

Original Expression

A=\sqrt {\frac{2x^5}{18}}\\\\ \text{put, x=1}\\\\A=\sqrt{\frac{2 \times 1^5}{18}}\\\\A=\sqrt{\frac{1}{9}}\\\\A=\frac{1}{3}\\\\\text{Equivalent Expression B}\rightarrow \frac{x^2}{3}\times \sqrt{x}\\\\\text{put,x=1}\\\\B=\frac{1^2}{3}\times \sqrt{1}\\\\B=\frac{1}{3}

Use the formula a2 – b2 = (a b)(a – b) to factor completely. what are the factors of 36x8 – 49? (9x4 – 1)(4x2 49) (36x4 – 7)(x2
zimovet [89]

The factors of 36x^8 – 49 are  (6x^4-7)(6x^4+7).

We are given to factor the following polynomial completely:

36x^8 – 49.

We have to find the complete factor of the given polynomial.

Completely factor means to continuously factor terms until they are in simple terms, meaning you are no longer able to factor

<h3>What is the formula for (a^2-b^2)?</h3>

The formula for (a^2-b^2)= (a+b) (a-b).

Therefore applying the given formula we have,

F=(6x^4)^2-7^2

F=(6x^4)^2-7^2\\F=((6x^4)-7)(6x^4)+7)

Thus, the required factors are

F=((6x^4)-7)(6x^4)+7)

Therefore,option (C) is correct.
