Which radical expressions are equivalent to the exponential expression below? Check all that apply.
(13 + 13)1/2
A. 169
IB. 125
O C. 26
D. 13 - 13
E. (13+13)2

The decimal expansion would be .27 repeated

Volume is length times width times height so
20 times 8 times 30 which is 4,800
surface area is ph (p is perimeter of base), h is height.
so perimeter would be length+length+width+width so 20+20+8+8 which is 56. so multiply 56 times 30 which is 1680. hope this !

That is correct 8.25 multiplied by 7 is 57.75
