(8.4 * 10^2) (2.5 * 10^6) associative property -> we can multiply these in whichever order we want 8.4 * 2.5 * 10^2 * 10^6 21 * 10^8 if your instructions said to put the answers in scientific notation, however, we are not done here 21 * 10^8 2.1 * 10 * 10^8 2.1 * 10^9

The product of ( 8.4 × 1 0 2 ) × ( 2.5 × 1 0 6 ) is 2.1 × 1 0 9 . This is found by multiplying the coefficients and adding the exponents of the powers of ten. The final answer is expressed in proper scientific notation.
