1.2 x 10^3
1.2 x 10^-3
5.6 x 10^4
5.6 x 10^-4
1.2 x 10^2
1.2 x 10^-2
5.6 x 10^2
5.6 x 10^-3

To solve these problems, you simply need to multiply or divide the given number by the exponent of 10.

1. 2 x 10^3 = 2 * (10 * 10 * 10) = 2,000
2. 1.2 x 10^-3 = 1.2 / (10 * 10 * 10) = 0.0012
3. 5.6 x 10^4 = 5.6 * (10 * 10 * 10 * 10) = 56,000
4. 5.6 x 10^-4 = 5.6 / (10 * 10 * 10 * 10) = 0.00056
5. 1.2 x 10^2 = 1.2 * (10 * 10) = 120
6. 1.2 x 10^-2 = 1.2 / (10 * 10) = 0.012
7. 5.6 x 10^2 = 5.6 * (10 * 10) = 560
8. 5.6 x 10^-3 = 5.6 / (10 * 10) = 0.056

What is 45,000,000 in scientific notation

45,000,000 in scientific notation is written as 4.5 x 10^7.

What's 320,500,000 in scientific notation

320,500,000 in scientific notation is written as 3.205 x 10^8.

The diagram represents the relationship of number sets. The four choices given will complete the diagram. Which BEST describes the set of numbers in block A? block a has 5/3, 0.63, and 0.012

Based on the given numbers in block A (5/3, 0.63, and 0.012), it can be inferred that the set of numbers in block A consists of decimal fractions in the range of less than 1. The best choice that describes this set of numbers is "Decimal Fractions less than 1."

ok the answer choices are integers, whole numbers, natural numbers, and rational numbers

Based on the given numbers in block A (5/3, 0.63, and 0.012), we can see that all of them are rational numbers.

Integers only consist of whole numbers and their negatives, so it does not include decimal fractions like the ones in block A.
Whole numbers include all non-negative integers, so it also does not include decimal fractions.
Natural numbers include all positive integers, so it also does not include decimal fractions or fractions like 5/3.
Rational numbers include all numbers that can be expressed as a fraction, including decimal fractions and fractions.

Therefore, the best choice that describes the set of numbers in block A is "Rational Numbers."

To solve these problems involving numbers in scientific notation, you can simply multiply the coefficient (the number before the "x") by the exponent of 10.
