You have the following product:
[tex]4.5*10^5\times2.4*10^{-2}[/tex]To simplify the previous expression, multiply the coefficients 4.5 and 2.4 and multiply the 10 factors by using the properties of exponents:
[tex]4.5*10^5\times2.4*10^{-2}=(4.5*2.4)*10^{5-2}=10.8*10^3[/tex]10.8 can be written as 1.08*10, then, you can write the previous result as follow:
[tex]10.8*10^3=1.08*10*10^3=1.08*10^4[/tex]Hence, the answer is 1.08*10^4
