2.13× blank = 21,300,000 what power of 10 would make this equation true
2.13x = 21,300,000
x = 21,300,000/2.13 = 10,000,000 = 10^7
Another way of doing this is to start at the decimal point and count how many digits you must move the decimal point to get to the end. That is 7 so it's 2.13E7
To find the power of 10 that would make the equation true, you need to determine the number of zeros in the number 21,300,000.
Since 2.13 multiplied by some power of 10 equals 21,300,000, we can equate the number of zeros in 21,300,000 to the power of 10.
Counting the zeros in 21,300,000, we see that there are seven zeros.
Therefore, the power of 10 that would make this equation true is 7.
To find the power of 10 that would make the equation true, we need to determine how many times we would need to multiply 2.13 by 10 to obtain 21,300,000.
To do this, we can divide 21,300,000 by 2.13:
21,300,000 ÷ 2.13 = 10,000,000
So, multiplying 2.13 by 10,000,000 will give us 21,300,000. This means that 10,000,000 is the power of 10 required to make the equation true.
