squared means multiply the base by itself.

The base is 3√7

so 3√7 x 3√7=3 x 3 x √7 x √7=3x3x7=9x7=63

I hated radicals as quickly as I discovered them. What you would be able to desire to do is ruin the seventy two right into a sq. selection and an entire selection that as quickly as expanded equivalent seventy two. it works suitable with the optimal a probability sq. #. For this difficulty the suitable one would be 36. it might look like 3* ?(36*2). you will take the sq. root of 36 this is 6 and bypass away the two. you will then multiply the three by potential of 6 getting 18. Your answer would be 18?2.

(3√7)^2 is 3^2 and √7^2 and 3^2 is 9 and √7^2 is 7, so its basically asking, (7)(9)

Think of the square root as a root of 1/2, then distribute the power of two. Voila.

square root(7) = 2.64575131

3 (2.64575131) = 7.93725393

(7.93725393)squared = 62.9999999

The answer is 62.9999999 or 63

3^2 then √7^2... then add them up.
