To write the expression using scientific notation, we first multiply the coefficients (2.5 * 4 = 10). Then we add the exponents of the powers of 10 (10^4 * 10^3 = 10^(4+3) = 10^7). Therefore, the expression in scientific notation is:
10 • 10^7
Which simplifies to:
1 • 10^8
Therefore, the answer is option C. 1 • 108.
