Question

step by step answer please​

Answer 1

Answer:

• $\boxed{ \sf \: \: 12x \: - 12}$

Solution:

$\sf \: \sqrt[4]{16} \: - \: 6x \: \sqrt[3]{343} \: + \: {18x}^{2} \sqrt[5]{243} \: - \: \sqrt{196}$

$\sf \: = \sqrt[4]{ {2}^{4} } \: - \: 6x \: \sqrt[3]{ {7}^{3} } \: + \: 18x \: \sqrt[5]{ {3}^{5} } \: - \: \sqrt{ {14}^{2} }$

$\sf \: = 2 \: - \:( 6x \: \times 7 ) \: + \: (18x \: \times 3)\: - \: 14$

$\sf \: = 2 \: - \:42x \: \: + \: 54x \: - \: 14$

$= \boxed{ \sf \: \: 12x \: - 12}$
