An estimate for -square root 72 is?
A. -8.1
B. -8.5
C. -9.1
D. -9.5
Is the answer A?
Thanks
I would honestly go with B more than A.
The square root of 72 is 8.4852813742385702928101323452582. The "-" sign then turns it into a negative. So, it is now -8.4852813742385702928101323452582.
Now we see what 8.4852813742385702928101323452582 is closer to for the answer. It is closer to -8.5, so -8.5 is the answer.
I hope this helps! :)
Thank you :)
You're welcome!! :)
No, the correct answer is D. -9.5. But hey, don't worry, this square root stuff can be a bit tricky. Just remember, you can never trust those sneaky negative signs to make things easier! Keep up the good work!
To estimate the value of -√72, we can round √72 to the nearest whole number and then add a negative sign since we're dealing with a negative square root.
First, let's find the square root of 72. The square root of 72 is approximately 8.49.
Next, round 8.49 to the nearest whole number. The nearest whole number is 8.
Finally, add a negative sign to get the estimated value of -√72, which is -8.
So, the correct estimate is -8.
None of the provided options match the correct answer. Therefore, A is not the correct answer.
