The equivalent expression is [tex]3x^4\sqrt{2}[/tex] . Option B
Given the expression
= [tex]\frac{18x\sqrt{14x^8} }{6\sqrt{7x^4} }[/tex]
Divide the multipliers, we have
= [tex]\frac{3x\sqrt{14x^8} }{7x^4}[/tex]
Let factorize the numerator in square root
= [tex]\frac{3x \sqrt{7x^4 * 2x^4} }{7x^4}[/tex]
Eliminate the like factor in both the numerator and denominator
= [tex]3\sqrt{2x^4}[/tex]
Let's bring forth the 'x' factor, we have
= [tex]3x^4\sqrt{2}[/tex]
Thus, the equivalent expression [tex]3x^4\sqrt{2}[/tex] . Option B
