5 x 10^3 + 2 x 10^2 + 8 x 10^1
The closest you can get by: Using Each Number Once With Powers: 10 th the second power - 4 th the third power=46 Using each Number Once Without Powers:(4*10)-3+2 Using an indefinite amount of each number:4-*10+(3*2)-(2+2+2)
7x10^3 + 4x10^2 + 3x10^1 + 9x10^0
Expanded Notation of 5,280 = (5 x 10^3) + (2 x 10^2) + (8 x 10^1) + (0 x 10^0)
They are 10 and 20
2 x 10-1 = 0.2 The negative powers are the reciprocals of the positive powers: 10-1 is the same as 1/101 10-2 is the same as 1/102 etc So: 2 x 10-1 = 2 x 1/101 = 2 x 1/10 = 2 / 10 = 0.2
To multiply powers with the same base, you add the exponents. For example, 10^2 x 10^3 = 10^5. Similarly, to divide powers with the same base, you subtract the exponents. For example, 10^3 / 10^5 = 10^(-2).
Expanded Notation written using the powers of 10 This is an extension of writing the equation in expanded notation! Therefore I will use the information from that to explain; First I'll do out a table showing powers 10^2 = 100 10 to the power of 2 is One Hundred (2 zero's-after the 1) So hopefully you see the pattern in the above table!
It is the second power.
1/100 = 10-2
powers of 10 are like this 10(small 1) 10(small 2) exetra i need help on the same question but atleast this might help someone
81.402 in expanded form using the powers of ten = (8 x 10^1) + (1 x 10^0) + (4/10^1) + (0/10^2) + (2/10^3)
It is 720000
5 x 10^3 + 2 x 10^2 + 8 x 10^1
3,282 = (3 x 10^3) + (2 x 10^2) + (8 x 10^1) + (2 x 10^0)
(3 x 100) + (2/10^1) + (9/10^2)
To write powers of ten (exponential form) you need to make sure you know that you are multiplying 10*10 each time, not 10*2 etc. An example of this 102 which equals 100 because 10*10 is 100.
