The number 6.13E−14 can be expressed as 6.13 × 10^(-14) in scientific notation.
Kendra finds the dimensions of a sticky note. She uses a meter stick to determine that the dimensions are 1.25×10−8 meters wide by 2.5×10−6 meters long. Use scientific notation to write the dimensions in millimeters. Note: 1 meter is equal to 1,000 millimeters. (1 point)
To write the dimensions in millimeters, we need to convert the meters into millimeters.
1 meter is equal to 1,000 millimeters.
The width is 1.25 × 10^(-8) meters. To convert it into millimeters, we multiply by 1,000:
1.25 × 10^(-8) meters * 1,000 millimeters/1 meter = 1.25 × 10^(-8) * 1,000 millimeters = 1.25 × 10^(-5) millimeters
The length is 2.5 × 10^(-6) meters. To convert it into millimeters, we multiply by 1,000:
2.5 × 10^(-6) meters * 1,000 millimeters/1 meter = 2.5 × 10^(-6) * 1,000 millimeters = 2.5 × 10^(-3) millimeters
So, the dimensions of the sticky note in millimeters are 1.25 × 10^(-5) millimeters wide by 2.5 × 10^(-3) millimeters long.
To write a number in scientific notation, we need to express it as the product of a coefficient and a power of 10.
The number 6.13E−14 can be rewritten as 6.13 * 10^(-14).
So, in scientific notation, the number 6.13E−14 is represented as 6.13 * 10^(-14).
To answer this, we need to understand scientific notation. Scientific notation represents a number with a decimal point followed by digits, multiplied by 10 raised to an exponent.
In this case, the calculator displayed the number 6.13E-14. The "E" represents "times 10 raised to the power of." So, 6.13E-14 means 6.13 times 10 raised to the power of -14.
To convert this to a decimal, we can multiply 6.13 by 10 raised to the power of -14.
Calculating that, we get:
6.13 x 10^-14 = 0.0000000000000613
Therefore, the number 6.13E-14 in scientific notation is equivalent to 0.0000000000000613 in decimal notation.
