Which of the following is the solution to the equation 25^(z – 2) = 125 ?
6 years agoHint: 25 = 5^2 and 125 = 5^3 ------------------- So 25^(z – 2) = 125 (5^2)^(z – 2) = 5^3 5^(2(z-2)) = 5^3 Now equate the exponents to get 2(z-2) = 3
6 years agoI'll let you finish up and solve for z
6 years ago7/2?
6 years agothat is 100% correct
6 years agoz = 3.5
6 years agoyes, 7/2 = 3.5, so they are the same thing
