Answer 1

2401
​
=
7
x

​

⇒7
x
=2401
⇒x=4

Answer 2

Step-by-step explanation:

Considering * as x then

$2401 = V {7}^{x} \\ {49}^{2} = V {7}^{x}$

Need more information

If the equation is

$2401 = { ( \sqrt{7} )}^{x} \\ {49}^{2} = {7}^{ \frac{x}{2} } \\ {7}^{4} = {7}^{ \frac{x}{2} }$

Hence

$\frac{x}{2} = 4 \\ x = 8$
