Answer:

x=0

Step-by-step explanation:

You are asked what is the number to be use as the exponent of [tex]7^{2}[/tex], in order to get as answer "1".

Use the property of exponents that sates that : [tex]a^0=1[/tex]

In your case [tex]a=7^2=49[/tex] so the exponent "x"must be = 0 (zero)

Answer:

The value of x in the given equation is 0.

Solution:

We know that any number with power 0 is 1  [tex](a^{0}=1)[/tex]

As given,

[tex]\left(7^{2}\right)^{x}=1[/tex]  

As per the formula, [tex](a^{m})^n = a^{m+n}[/tex]

Here a is 7; 2 is m and x is n.

On substituting the values,  

[tex](7)^{2\times x}=1[/tex]

[tex](7)^{2\times x}=7^{0}[/tex] (//any power of 0 is 1)

Hence from both the side we get,

[tex](2\times x) = 0[/tex]

So, x = 0.
