To express the expression (7x10^4)x(5x10^2) in scientific notation, we can multiply the coefficients (7x5) and combine the exponents (10^4 x 10^2).
The coefficient multiplication gives us 7x5 = 35.
The exponent combination gives us 10^(4+2) = 10^6.
Therefore, the expression in scientific notation is 35x10^6.
