Yes, for a single-digit number, moving the decimal to the left (number to the right) creates a value that has an exponential value less than 1.
Decimal values less than 1 (100) would be multiples of negative exponents (e.g. 10-1 = 1/10) whereas those more than 1 have positive exponents (e.g. 10 = 101, 100 = 102).
9.72 x 10-5 You put the decimal behind the first digit. Then count the number of places the decimal moved from its original position. This number becomes the exponent of the 10. If you move the decimal to the left, it is a positive number for the exponent. To the right, it is a negative exponent.
A number in scientific notation should have one number before the decimal place then two after. You move the decimal so this is true, then the number of places you moved the decimal will be the exponent. If you move the decimal to the right your exponent will be negative, if you move it to the left it will be positive. In this case you would move the decimal 5 places so you have 1.05x10^-5.
scientific notation is a single digit or digit and decimal followed by the letter E and the exponent of ten to be multiplied by the number.(or number of places to shift the decimal point to the right(positive exponent) or left(negative exponent)) 32000000 would be expressed as 3.2E7
No, it will not.
To put a number into scientific notation, first identify the decimal point's position to get a number between 1 and 10. Then, write this number followed by the multiplication sign "×" and 10 raised to the power of the decimal places the decimal point moved. If the decimal point moves to the left, the exponent is positive, and if it moves to the right, the exponent is negative.

When you have a number raised to a negative exponent, you move to the left rather than the right in decimal places. E.g. 103 = 1000 10-3 = 0.001 More specifically, when you have a negative exponent, you are taking the reciprocal of what the positive exponent would give. 24 = 16, but 2-4=(1/16) ■

5.61 x 102 , you just move the decimal so that the original number is greater than or equal to one but less than 10 then multiply that by 10 to the power of the number of decimal places you had to move. If you moved the decimal to the left, the exponent is positive, if you moved the decimal to the right, the exponent is negative.
3.86 x 105 Scientific notation is useful to get rid of seeing the zeros in a number. Count how many places you need to move your decimal place to have the last non zero number in the ones place and the rest of the numbers to the right of the decimal. The number of movements will be the exponent. When you are moving the decimal place to the left your exponent will be positive, when moving the decimal right, your exponent will be negative.
To change a number from standard to scientific notation, move the decimal point to create a number between 1 and 10. Count the number of places you moved the decimal point to get the power of 10. If you moved it to the left, the exponent is positive, and if you moved it to the right, the exponent is negative.
Count how many places you move the decimal point until you get the number 6.7.If you move the decimal place to the left, the exponent is a positive number, but in this case you have to move the decimal point 5 places to the right so you will have a negative exponent.Answer: 6.7 x 10-5
Move 10 decimal places to the right to get: 7 x 10-10 The exponent is negative since the leading nonzero digit takes place 10 decimal places on the right of the decimal places
