\huge\text{Hey there!}


\huge\boxed{\mathsf{(3.4 * 10^4)(4.5 * 10^3)}}\\\huge\boxed{\mathsf{\rightarrow 3.4*10^4 * 4.5 * 10^3}}


\huge\boxed{\mathsf{10^4}}\\\huge\boxed{= 10*10*10*10}\\\huge\boxed{= 100*100}\\\huge\boxed{= 10,000}\\\\\\\huge\boxed{\mathsf{10^3}}\\\huge\boxed{=10*10*10}\\\huge\boxed{= 100*10}\\\huge\boxed{= 1,000}


\huge\boxed{\rightarrow\mathsf{3.4* \bold{10,000} * 4.5 * \bold{1,000}}}}


\huge\boxed{\mathsf{3.4*10,000}}\\\huge\boxed{= 34,000}\\\\\\\huge\boxed{\mathsf{4.5*1,000}}\\\huge\boxed{{= 4,500}}}


\huge\boxed{\mathsf{\rightarrow\bf 34,000*4,500}}\\\huge\boxed{\rightarrow\mathsf{ORIGINAL \ ANSWER: \frak {153,000,000}}}}


\huge\boxed{\textsf{Your answer: }\mathsf{153*10^6}}\huge\checkmark
