Step-by-step explanation:
you still add'em.
Answer:
43,000: 4.3×10^4
0.0072: 7.2×10^-3
0.0000901: 9.01×10^-5
Step-by-step explanation:
scientific notation: a×10^b, where should be 0<a<10
Step 1. Count the zeros
Step 2. Look at the number left, and determine whether or not it fits in the range of [a]. If not, we divide or multiply 10 to get it fit
------------------------
43,000: 4.3×10^4 (since 43 does not fit, we divide by 10 to get it fit)
0.0072: 7.2×10^-3 (since 0.72 does not fit, we multiply 10 to get it fit)
0.0000901: 9.01×10^-5 (since 0.901 does not fit, we multiply 10 to get it fit)
Hope this helps!! :)
Please let me know if you have any question
Both numerator and denominator are a sum of 51 terms, counted skipping 4s (numerator) and 2s (numerator).
So, you have
Use the linearity of sum to rewrite this as
So, as you can see, the numerator is exactly twice the numerator: you can cancel out the sum and you have
7 4/5 multiply 4/5 by 2 which will be 7 8/10+ 12 1/10 whigh will end up as 19 9/10
