Answer:
√53 lies between 7.2 and 7.3
Step-by-step explanation:
To estimate the √53 between two numbers to the tenths place, the steps include
1.) Identify perfect squares that bound the number 53: 7² = 49 and 8² = 64
2.) Estimate between two whole numbers: between 7 and 8
3.) Determine the closer whole number: the root is closer to 7 because 53 is closer to 49 than to 64.
4.) Find the squares of tenths:
7.1²= 50.41
7.2²= 51.84
7.3²= 53.29
7.4²= 54.76
Hence, it is evident that √53 lies between 7.2 and 7.3
It is also clear that the required square root is closer to 7.3 than 7.2 though.

602.88cm(to the third power but there is no exponent on keyboard)
Known that,
x = z
Also known that,
x + y = 10
Substituting value of x,
z + y = 10
Hence, proved.
