Answer: 5
Explanation Let's simplify the expression: √25^(3x) = √(5²)^(3x) = √(5^(6x)) = 5^(3x) Now, divide by 5^(6x-2): 5^(3x) / 5^(6x-2) = 5^(3x - 6x + 2) = 5^(-3x + 2) For this to equal one of the given options (5, 10, 15), let's see if -3x + 2 = 1 (for 5¹ = 5): -3x + 2 = 1 -3x = -1 x = 1/3 Then, 5^(-3(1/3) + 2) = 5¹ = 5

Answer: 2
Explanation Let's calculate: 1. 4^0.36 2. 16^0.07 = (4²)^0.07 = 4^(2*0.07) = 4^0.14 Now, multiply: 4^0.36 × 4^0.14 = 4^(0.36 + 0.14) = 4^0.5 4^0.5 = √4 = 2

Answer: 26, 14
Explanation Let's denote the smaller number as x and the larger number as x + 12. Given: x + (x + 12) = 40 Combine like terms: 2x + 12 = 40 Subtract 12 from both sides: 2x = 28 Divide by 2: x = 14 The larger number is x + 12 = 14 + 12 = 26 The numbers are 26 and 14.
