Identify base, number, and unknown exponent: Identify the base (b), the number (x), and the unknown exponent (y) in the logarithmic equation log_(5)625 = y. Here, b = 5 and x = 625. We need to find the value of y such that 5^y = 625.Recall logarithm and exponential form: Recall that the logarithm log_(b)x = y is equivalent to the exponential form b^y = x. We need to find the power y to which the base 5 must be raised to get 625.Determine if 625 is a power of 5: Determine if 625 is a power of 5. We know that 5^2 = 25 and 5^4 = 625. Therefore, 5 raised to the power of 4 equals 625.Write exponential equation using base 5 and exponent 4: Write the exponential equation using the base 5 and the exponent 4 to equal 625. The equation is 5^4 = 625.Value of y in logarithmic equation: Since 5^4 = 625, the logarithmic equation log_(5)625 equals 4. This means that the value of y in the equation log_(5)625 = y is 4.
