Question

please answer to this question with clear explanation ​

Answer 1

Step-by-step explanation:

$\sqrt{ {5}^{4} } \times 14 - 6 \times 7 + {4}^{x} = {18}^{2} = >$

${5}^{ \frac{4}{2} } \times 14 - 42 + {4}^{x} = 324 = >$

${5}^{2} \times 14 - 42 + {4}^{x} = 324 = > 25 \times 14$

$- 42 + {4}^{x} = 324 = > 350 - 42 + {4}^x =$

$324 = > {4}^{x} = 324 - 308 = 16 = >$

${4}^{x} = {4}^{2} = > x = 2$

Hope it helps you.
