Scientific Notation Quiz questions

1) 18,000,000=

1.8*10^7

18*10^0

180*10^7

1800*10^8

The correct answer is 1.8*10^7 because it represents the number 18,000,000 in scientific notation. In scientific notation, a number is written as a decimal between 1 and 10 (in this case 1.8) multiplied by a power of 10 (in this case 10^7). This means that 1.8*10^7 is equal to 18,000,000.

Explanation

The correct answer is 1.8*10^7 because it represents the number 18,000,000 in scientific notation. In scientific notation, a number is written as a decimal between 1 and 10 (in this case 1.8) multiplied by a power of 10 (in this case 10^7). This means that 1.8*10^7 is equal to 18,000,000.

2) Mark t if statement is true and f if its false 17,000,000=170*10⁶

True

False

The statement is false because 17,000,000 is equal to 17 * 1,000,000, not 170 * 106.

Explanation

The statement is false because 17,000,000 is equal to 17 * 1,000,000, not 170 * 106.

3) 1*10²²

Standard

Scientific

Non

The given answer "scientific" suggests that the number 1*1022 is written in scientific notation. In scientific notation, numbers are expressed as a product of a decimal number between 1 and 10 and a power of 10. In this case, the decimal number is 1 and the power of 10 is 22. Therefore, the number can be written as 1 x 10^22, which is a common form used in scientific calculations and representing very large or very small numbers.

4) 12*10¹⁰

Standard

Scientific

Non

The given question asks for the type of calculator that would be suitable for solving the expression 12*1010. Since this is a multiplication problem involving large numbers, it would be more appropriate to use a scientific calculator, which is designed to handle complex calculations and display the result in scientific notation if necessary. A standard calculator may not have the capability to accurately calculate and display the result for this type of calculation.
