Answers & Explanations- New AND Free SAT Math practice test- 201-206
1. A: 104=10.10.10.10, or 10,000.
2. C: When multiplying terms with the same base, the exponents should be added. Thus, 104 . 102=106.
3. D: When dividing terms with the same base, the exponents should be subtracted. Thus, x5/x2 =x3.
4. D: The decimal will be moved to the right 9 places. Thus 7 zeros will be added to the right of 823, giving 8,230,000,000.
5. B: Moving the decimal to the right of the digit, 8, gives the equivalent expression, 8.3×104, since there are 4 digits to the right of the 8.
6. B: Moving the decimal to the right of the 8 gives 8.75×10-3, since the decimal must be moved 3 places to the right.
