i am guessing that this is \[(3\times 10^6)(8\times 10^{4})\]

multiply \(3\times 8=24\) and \(10^6\times 10^{4}=10^2\) so the first thing you get it \[24\times 10^2\] but in scientific notation you need to write it as \[2.4\times 10^3\]

I assume that is really \[(3*10^6)(8*10^{4})\] Multiplying the 10^{num} pats is easy, just add the exponents. Multiply the other two, combine with the new exponent part: \[(3*10^6)(8*10^{4})\ = (24 * 10^{(64)})\] Now adjust the first part to make it between 1 and 10 and adjust the exponent to match. That gives you \[ 2.4 * 10*10^2 = 2.4*10^3\] because you divided the first part by 10 and increased the last part by 10 to keep the value the same.

first part = mantissa

Engineering notation is like scientific notation, except the exponent is always a multiple of 3 — makes it a bit easier when using kilo or mega or whatever prefixes.
