Exponents
Example: 12x12x12=123
Nope! place value is a numeric word! Place value can be used in multiplication but it's not a multiplication word!
To express a number in expanded notation, you first need to divide it by a power of 10 such that the units is the greatest place value. In this case, you would divide by 100 to get 8.523. The next step is to add that power of ten to the sum as a multiplication. We use 100, which is the second power of 10. This can be written as 102. Thus 852.3 can be written in expanded notation as 8.523x102
The value of 36*X is directly dependant on the value of X. In terms of common mathematical notation, the multiplication of a variable by a constant is implied, meaning that 36*X is the same as simply 36X
To write a number in scientific notation you first need to divide the number by a power of 10 such that the answer has units as the greatest place value. In this case, you can divide by 100,000 to get 6.35. The next step is to represent this power of 10 next to the number as a multiplication. We use 100,000 which is 105. Thus, 635,000 in scientific notation is 6.35x105
The Romans probably wrote it out as (((M)))(X) because:- Numerals in single brackets indicate multiplication by a 1,000, numerals in treble brackets indicate multiplication by 100,000 and superscript numerals indicate multiplication by that particular numeral value. Hence:- (((M)))(X) = 100,000*1,000*1,000*10 = 1,000,000,000,000 or as 1.0*1012 in standard notation
The rf value is shorthand for the retention value of a substance. It is used in chromatography to determine the components of an unknown sample.
What is the value of the exponent in the scientific notation expression for 0.0000083?
It is the representation of a value in mathematical notation.
To express a number in scientific notation you first have to divide that number by a power of 10 such that the greatest place value digit is units. In this case we can divide by 100 to get 2.47. The next step is to take the power of 10 we used (in this case 100, or 102) and write it along side the number as a multiplication. Thus, 247 in scientific notation is 2.47x102
It is: 2.45*10^8 in scientific notation
It has a value of 1.0*1066 in scientific notation
Exponents are shorthand for repeated multiplication of the same thing by itself. For instance, the shorthand for multiplying three copies of the number 5 is shown on the right-hand side of the "equals" sign in (5)(5)(5) = 53. The "exponent", being 3 in this example, stands for however many times the value is being multiplied. The thing that's being multiplied, being 5 in this example, is called the "base".
