5/7^3 = 5(7^x)<br> Thank you for helping!!
SIZIF [17.4K]

When solving this equation you get x = -3.

To solve this, simply follow the order of operations for solving.

\frac{5}{7^{3}}  = 5(7^{x} ) ----> start by dividing both sides by 5

\frac{1}{7^{3}}  = (7^{x} ) -----> Now you can transform the front side of the equation to use negative exponents.

7^{-3} = 7^{x}

Since both x and -3 are the powers of x, we can eliminate the 7 and just make the exponents equal.

-3 = x
