Answer:

x=81

Explanation:

we know that

Observing the graph

The number
√(x) lie on the interval----> (9.3,9.4)

so

Square root of x is greater than 9.3 and is less than 9.4

Round square root of x to the nearest whole number

√(x)=9 ----> because square root of x is less than 9.5

squared both sides

x=9^(2)

x=81
