8. Step 1: Express both sides of the equation with the same base. The equation is 25^3x-5 = 5. Since 25 = 5^2, we can rewrite the equation as: (5^2)^3x-5 = 5^1 Step 2: Apply the power rule for exponents, (a^m)^n = a^mn. 5^2(3x-5) = 5^1 5^6x-10 = 5^1 Step 3: Equate the exponents, as the bases are now the same. 6x-10 = 1 Step 4: Solve for x. 6x = 1 + 10 6x = 11 x = (11)/(6) The value of x is: (11)/(6) 9. Step 1: Rewrite the expression using reciprocals. The expression is (5)/(0.6699) - (1)/(4.231). This can be written as 5 × (1)/(0.6699) - (1)/(4.231). Step 2: Find the reciprocal values. Using a calculator to simulate reciprocal table values: (1)/(0.6699) ≈ 1.4928 (1)/(4.231) ≈ 0.2364 Step 3: Substitute the reciprocal values into the expression and calculate. 5 × 1.4928 - 0.2364 7.4640 - 0.2364 7.2276 The evaluated expression is: 7.2276 10. Step 1: Evaluate the logarithm. The given equation is 0.00001 = 2y. Assuming the base of the logarithm is 10 (common for "log" when no base is specified). First, express 0.00001 as a power of 10: 0.00001 = 10^-5 Now, evaluate _10 (10^-5): _10 (10^-5) = -5 Step 2: Solve for y. Substitute the value of the logarithm back into the given equation: -5 = 2y Divide by 2 to find y: y = (-5)/(2) y = -2.5 The value of y is: -2.5 Send me the next one 📸
