Answer:
R= 22537
Step-by-step explanation:
700.000 = 7 . 10 . 10 . 10 . 10 . 10
We know that equal bases sum the exponents, so,
7 . 10^(1 + 1 + 1 + 1 + 1)
7 . 10^5 = 700.000
But we can also say:
(7 . 10) . 10^4
or
(70 . 10) . 10³
or
(700 . 10) . 10²
or
(7000 . 10) . 10
As we can see, the alternative C shows (7 . 10) . 10^4 which can be a correct ans, so, alternative C.
You have correctly answered the last 3 questions in this list, so the answer to the first one left blank is no.
This is because 455,000 rounded to the nearest ten thousand is 460,000, rounding to 456,000 is rounding to the nearest one thousand.
I hope this helps!
