Without using mathematical tables, evaluate the following leaving your answers in standard form. a) M/N where M = 7.2 x 10^-3 and N = 5 x 10^-11. b) square root of (0.81 x 10^-5) / (2.25 x 107). c) P/Q where P = 3.6 x 10^-3 and Q = 2.25 x 106. d) square root of (8.1 x 103) / (1.44 x 104)

Step 1: Separate the numerical parts and the powers of 10. (8.1 × 10^3)/(1.44 × 10^4) = ((8.1)/(1.44)) × ((10^3)/(10^4)) Step 2: Divide the numerical parts. (8.1)/(1.44) = 5.625 Step 3: Divide the powers of 10 using the exponent rule (a^m)/(a^n) = a^m-n. (10^3)/(10^4) = 10^3-4 = 10^-1 Step 4: Combine the results to get the answer in standard form. 5.625 × 10^-1 The final answer is 5.625 × 10^-1. Send me the next one 📸
