Best Answer

To evaluate the expression (4x10^4)(2x10^5), you first multiply the numbers 4 and 2 to get 8. Then, you multiply the powers of 10 by adding the exponents, which gives you 10^(4+5) = 10^9. Therefore, the final answer is 8x10^9.

Mutiply the digits and add the powers and so (4*10^4)(2*10^5) = 8*10^9
