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
Answer: not sure how helpful this is, but the second one is correct (if it's the one that's corresponding to the blue line). The pink line, however, is incorrect if it is corresponding to the first equation. The first equation must have a y-intercept of 1.
