Four students work to find an estimate for square root 54. who is closest to finding the true estimate? (1 point)
rhonda: "use square root 16 and square root 25 to estimate."
ricardo: "i use square root 25 and square root 36."
riley: "it should be between square root 36 and square root 49."
rhiannon: "use square root 49 and square root 64 to estimate."***

Step-by-step explanation:

We know that they are working to find the estimate for the square root of 54.

The proper way to do it is to find a number which sqaure power results near 54.

So, 6x6 = 36, 7x7 = 49, 8x8 = 64.

You can observe that 54 is between the square power of 7 and 8. Also, the square power of 7 is 49, which is immediately above 54.

Therefore, the best estimation to the root of 54 is 7, because its square power is nearest.

That means Rhiannon, because he's using the right interval to do the estimation between 49 and 64, or between 7 and 8.
