Expert Solution

Answer to Problem 80E

  7.1×1014=710000000000000

Explanation of Solution

Given information:

Given number is,

  7.1×1014

Calculation:

Consider the expression,

  7.1×1014

In this case, since the exponent of 10 is 14, to expand from scientific notation to decimal notation, move the decimal 14 places to the right.

  7.1×1014=7.1×1000000000000007.1×1014=710000000000000

(b)

To determine

To write: given number in decimal notation.

Expert Solution

Answer to Problem 80E

  6×1012=6000000000000

Explanation of Solution

Given information:

Given number is,

  6×1012

Calculation:

Consider the expression,

  6×1012

In this case, since the exponent of 10 is 12, to expand from scientific notation to decimal notation, move the decimal 12 places to the right.

  6×1012=6×10000000000006×1012=6000000000000

(c)

To determine

To write: given number in decimal notation.

Expert Solution

Answer to Problem 80E

  8.55×103=0.00855

Explanation of Solution

Given information:

Given number is,

  8.55×103

Calculation:

Consider the expression,

  8.55×103

For negative exponents, move the decimal in the opposite direction.

Here, the exponent is 3 , so move 3 decimal places in the opposite direction.

  8.55×103=0.00855

(d)

To determine

To write: given number in decimal notation.

Expert Solution

Answer to Problem 80E

  6.257×1010=0.0000000006257

Explanation of Solution

Given information:

Given number is,

  6.257×1010

Calculation:

Consider the expression,

  6.257×1010

For negative exponents, move the decimal in the opposite direction.

Here, the exponent is 10 , so move 3 decimal places in the opposite direction.

  6.257×1010=0.0000000006257
