Which exponential equation is equivalent to this logarithmic equation? log5 x - log5 25 = 7

A. 7^9=x
B. 5^9=x
C. 7^5=x
D. 5^5=x

Step-by-step explanation:

we are given a logarithmic equation

simplify the log:

add 2 to both sides:

remember that,

so we obtain:

hence,

our answer is B)

sorry I need points

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
