benzhi asked · 21 Dec 2012
pls anyone.. calculate for goodness sake
JD2016: The confusing thing here is that the answer has not been simplified! You wouldn't normally leave 54/26 as the answer - it can be reduced to 27 /13 or 2 1/13 which LOOKS like the third answer but isn't.

1. Mathematics
Given the log of A exceeds that of B by 4, find the correct statement about A and B.
- A is 4000 times the value of B.
- A is 10,000 times the value of B.
- A is 1000 times the value of B.

jamesmuendo asked · 5 Jun 2016
Do the calculation please
Ivor: It is assumed that the log is base 10. So 10 to power 4 = 10*10*10*10 = 10000

pls explain me
squareroot: volume 4000 litres = 4 cubic meters volume = length - width - height so 4 cubic meters = 4m-2m-? then. 4 cubic meters = 4m-2m-0.5m answer is 0.5m or 50cm

this shape looks like rhombus
supermas93: All side equal is not the only property of the rhombus. A Rhombus is a quadrilateral in which the diagonals are perpendicular and bisect each other. This is not the case.
