One symbol thing off roughly it takes light less than 0.00000003 of a second to travel 1 m distance Express this number in the form of a * 10 ^ n where 1 is greater a greater 10 and is one digit number
To express the number in the form of a * 10^n, we need to move the decimal point until there is only one non-zero digit to the left of it and count the number of decimal places shifted.
In this case, we need to shift the decimal point 8 places to the left to have only one non-zero digit (3) to the left of it:
0.00000003 = 3 * 10^(-8)
Therefore, the number 0.00000003 can be expressed as 3 * 10^(-8) in the requested form.
To express the number in the form of a * 10 ^ n, we need to convert 0.00000003 to a number between 1 and 10.
First, let's count the number of decimal places in 0.00000003. There are 8 decimal places.
To move the decimal point to the right, we multiply by 10^8:
0.00000003 * 10^8 = 3
Now, we have the number 3.
Since 3 is a one-digit number and greater than 1, we can express it in the desired form:
3 * 10^-8
To express the given number in the form of a * 10^n, where "a" is greater than 1 and is a one-digit number, we need to first convert the given number into scientific notation.
The value mentioned, "less than 0.00000003," can be written as 3 x 10^-8.
Since the number is less than 1, we can rewrite it as 3/10^8 in decimal form.
Now, we have the number in the form "a/10^n," where "a" is 3 and "n" is 8.
To express it in the required form with "a" greater than 1 and a one-digit number, we can multiply both the numerator and denominator by 10 to make the denominator a single-digit number:
(3/10^8) x (10^1/10^1) = 30 x 10^-9
Now, we have the number expressed as 30 x 10^-9, which satisfies the condition.
