A question: (5.3 x 10 to the 6th power) + 8.2 10 to the 6th power) A solution: Multiply 10 x 10 6 times to get rid of the two powers. (5.3 x 1,000,000) + (8.2 x 1,000,000) Multiply inside the parenthises. (5,300,000) + (8,200,000) Add: 13,500,000. A answer: 13, 500,000.
B question: (6.5 x 10 to the 7th power) / (5 x 10 to the 3rd power) B solution: Again, get rid of the powers. (6.5 x 10,000,000) / (5 x 1,000) Multiply inside the parenthesis: (65,000,000) / (5,000) Divide: 13,000 B answer: 13,000.
C question: (4.6 x 10 to the 6th power) (3 x 10 to the 5th power) / (2 x 10 to the 7th power) C solution: Get rid of powers: (4.6 x 1,000,000) (3 x 100,000) / (2 x 10,000,000) Multiply: (4,600,000) (300,000) / (20,000,000) multiply in the left side: (1,380,000,000,000) / (20,000,000) divide: 69,000 C answer: 69,000
