evaluate. exspress your answer in scientific notation 38,000,000-4.7*10^6
To evaluate the expression, we perform the subtraction:
38,000,000 - 4.7 * 10^6 = 33,300,000
Expressing this in scientific notation, we can write 33,300,000 as 3.33 * 10^7.
To evaluate the expression 38,000,000 - 4.7 * 10^6 in scientific notation, we can start by performing the subtraction:
38,000,000 - 4.7 * 10^6 = 33,300,000.
Now we need to express the answer in scientific notation. In scientific notation, we write a number as a decimal between 1 and 10, multiplied by a power of 10.
33,300,000 can be written as 3.33 * 10^7 in scientific notation.
Therefore, the answer is 3.33 * 10^7.
To evaluate the expression 38,000,000 - 4.7 * 10^6 and express the answer in scientific notation, you can follow these steps:
Step 1: Subtract the two numbers:
38,000,000 - 4.7 * 10^6 = 38,000,000 - 4,700,000 = 33,300,000
Step 2: Convert the result to scientific notation. In scientific notation, a number is expressed as the product of a decimal number between 1 and 10 (the coefficient) and a power of 10:
33,300,000 can be written as 3.33 * 10^7
Therefore, the evaluation of the expression 38,000,000 - 4.7 * 10^6 in scientific notation is 3.33 * 10^7.
