Answer:
O E. 225 in²
Step-by-step explanation:
I know
as a decimal is 0.7777778 and I know
as a decimal is 0.88889. Which one is bigger? 0.7778 or 0.8889. 0.8889 is bigger so your answer is 7/9<8/9
49^2m-m : Not equivalent
7^2m-2m : Not equivalent
7^2m-m : Not equivalent
This is actually a trick question. All of the following are actually false statements. Want to know why? Let me show you.
For exponents, if you are dividing a number to some power (i.e 5^3) by the SAME number to a different power (i.e 5^2), then the expression is 5^3-2 or 5^1 = 5. This is true for any number a such that a^b ÷ a^c = a^b-c.
Since 7 and 49 are not the same number, this rule does not apply and thus cannot be simplified any further.
Let me prove why. 5^3 = 125, and 5^2 = 25, and 125 ÷ 25 = 5. This is also the same as 5^3-2 = 5^1 = 5. We just proved this as so.
But, what about 7 and 49, or 2 different numbers. Well it doesn't apply. 7^3 = 343, and 49^2 = 2401, and 343 ÷ 2401 ≈ 0.14. Thus, this is NOT equal to 7^3-2 which is 7. We just proved that a^y ÷ b^z ≠ a^y-z. Congratulations!
Hope this helped!
You can answer it in fraction or decimal.
Fraction: In fraction, write 9 above 917 like this: 9/917. That is the answer in fraction.
Decimal: In decimal, do the long-division algorithm. You should get 0.009815.
