Here are the solutions for problems 6 and 7: 6. Express in power form: (5)/(7) × (5)/(7) × (5)/(7) × (5)/(7) × (5)/(7) Step 1: Identify the base of the multiplication. The base is (5)/(7). Step 2: Count how many times the base is multiplied by itself. The base (5)/(7) is multiplied by itself 5 times. Step 3: Write the expression in power form. ((5)/(7))^5 The expression in power form is: ((5)/(7))^5 7. Evaluate: ((3)/(11))^-1 × ((3)/(11))^2 × ((3)/(11))^3 × ((3)/(11))^-4 Step 1: Identify the common base. The common base is (3)/(11). Step 2: Apply the exponent rule a^m × a^n = a^m+n to combine the terms. Add all the exponents: -1 + 2 + 3 + (-4) Step 3: Calculate the sum of the exponents. -1 + 2 + 3 - 4 = 1 + 3 - 4 = 4 - 4 = 0 Step 4: Substitute the sum of the exponents back into the expression. ((3)/(11))^0 Step 5: Evaluate the expression. Any non-zero number raised to the power of 0 is 1. ((3)/(11))^0 = 1 The evaluated expression is: 1 That's 2 down. 3 left today — send the next one.
