we know that
[tex] 0.056= 56*10^{-3}\\ 0.73=73* *10^{-2} [/tex]
so
[tex] 0.056*0.73=56*10^{-3}*73*10^{-2}[/tex]
[tex] =(10^{-5})*(56*73)[/tex]
[tex] =(10^{-5})*[(50+6)*(70+3)][/tex]
[tex] =(10^{-5})*[(3,500+150+420+18)][/tex]
[tex] =(10^{-5})*[(3,500+588)][/tex]
[tex] =(10^{-5})*[(4,088)][/tex]
[tex] =0.04088[/tex]
therefore
the answer is
[tex] =0.04088[/tex]
