Answer:
(5x10^2)+(3x10^1)+(8x10^-1)+(2x10^-2)
Step-by-step explanation:
Any number that we can write as a decimal number, between 1.0 and 10.0, multiplied by a power of 10, is said to be in standard form.
So instead of the writing 500 which is what you would get by multiplying 5 by 100, for it to be in standard form it would be written as 5 multiplied by 10 raised to the second power or 5x10^2
so on and so forth.
Answer:
(5×100)=(5×10^2)
why is because of the two zeros after the one. if it was an ordinary number like 5678, the answer will be 5.6×10^3 because of the three numbers after the 5
(3×10)=(3×10^1)
(8×0.1)=(8×10^-1) it is raised to the power of -1 because its a decimal number
(2×0.01)=(2×10^-2)
