The answer is 6.0 x 10^-44.
(4 x 10^-12 )(3 x 10^-8) = 12 x 10^-20 = 1.2 x 10^-19
(1.2 x 10^-19) / (2 x 10^24) = 0.6 x 10^-43 = 6.0 x 10^-44

4^x / 2^(5-x) = 2^(4x) / 8^(x-3) 4^a = 2^2a, so: 4^x = 2^2x once you divide exponents with an identical base, you subtract the exponents. meaning: 2^2x / 2^(5-x) = 2^(2x-(5-x)) = 2^(3x-5) For the different section, 8^b = 2^3b, so: 8^(x-3) = 2^[3(x-3)] once you divide exponents with an identical base, you subtract the exponents. meaning: 2^(4x) / 2^(3x-9) = 2^(4x-(3x-9)) = 2^(x+9) Our new equation is: 2^(3x-5) = 2^(x+9) meaning: 3x-5 = x+9 3x = x+14 2x = 14 x = 7
