Answer to Problem 14CR

8.917×10−4

Explanation of Solution

In order to convert numbers to scientific notation, we must follow the following rules:

Use a single number before the decimal point. All other numbers will be placed after the decimal point.

The basis of expression will be the 10^t^h power. The powers can be any integer number.

From the second number, 4 significant figures.

Then, significant figures must be kept.

The given number:

Calculate the basis numbers (2.7918.219) = 0.3395790

Dividing the powers:

The tenth base:

10(−5−3)= 10−8

Keep only 4 significant numbers 0.3395790 , 5 must be rounded up to 0.3396

0.3396 = 3.396×10−1

Final expression

= (3.396×10−1)( 10−8) = 3.396×10−9

Thus, the scientific notation will be 3.396×10−9 .

Then, significant figures must be kept.

The given number:

Calculate the basis numbers (2.7918.219) = 0.3395790

Dividing the powers:

The tenth base:

10(−5−3)= 10−8

Keep only 4 significant numbers 0.3395790 , 5 must be rounded up to 0.3396

0.3396 = 3.396×10−1

Final expression

= (3.396×10−1)( 10−8) = 3.396×10−9

Thus, the scientific notation will be 3.396×10−9 .

Chapter 3, Problem 14CR

(a)

Interpretation Introduction

Interpretation : To convert the given number 0.0008917 to standard scientific notation.

Concept Introduction : Scientific notation for a number is written in such a way that large numbers are written in small decimal form which is then multiplied by the power of 10.

For numbers less than 1, the power of 10 in scientific notation has negative exponent and for numbers greater than 1, the power is either zero or has positive exponent.

Answer to Problem 14CR

8.917×10−4

Explanation of Solution

In order to convert numbers to scientific notation, we must follow the following rules:

Use a single number before the decimal point. All other numbers will be placed after the decimal point.

The basis of expression will be the 10^t^h power. The powers can be any integer number.

The given number: 0.0008917

Must be converted, so select the first number, ensure the power is correct.

8.917 will be the basis. Since, the decimal shifts 4 positions to the right, the power of ten will be −4 . Thus, the scientific notation is 8.917×10−4 .

8.51×107

Explanation of Solution

In order to convert numbers to scientific notation, we must follow the following rules:

Use a single number before the decimal point. All other numbers will be placed after the decimal point.

The basis of expression will be the 10^t^h power. The powers can be any integer number.

The given number:

85100000

Must be converted, so select the first number, ensure the power is correct.

Explanation of Solution

In order to convert numbers to scientific notation, we must follow the following rules:

Use a single number before the decimal point. All other numbers will be placed after the decimal point.

The basis of expression will be the 10^t^h power. The powers can be any integer number.

For a multiplication or division, significant figures rules must be followed.

The total amount of significant figures in the final result must be equal to the least amount of significant figures in the numbers multiplied or divided.

From the first number, 4 significant figures

From the second number, 4 significant figures.

Then, 4 significant figures must be kept.

The given number:

Calculate the basis numbers (5.751×2.119) = 12.186369

Multiply the powers:

The tenth base:

10(5−4)= 101=10

Thus, the number becomes 121.863

Keep only 4 significant numbers 121.863, bold digitmust be rounded up. Since, it is followed by digit 6 which is greater than 5, the digit 8 is rounded up to 9. The number becomes 121.9.

Thus, the scientific figure will be 1.219×102
