Answer:
8.55 × [tex]10^{7}[/tex]
Step-by-step explanation:
Given
7.9 × [tex]10^{7}[/tex] + 6.5 × [tex]10^{6}[/tex] ( factor out [tex]10^{6}[/tex] )
= [tex]10^{6}[/tex]( 7.9 × [tex]10^{1}[/tex] + 6.5)
= [tex]10^{6}[/tex](79 + 6.5)
= [tex]10^{6}[/tex] × 85.5
= [tex]10^{6}[/tex] × 8.55 × [tex]10^{1}[/tex]
= 8.55 × [tex]10^{7}[/tex]
