Answer: Award a touch for X
Step-by-step explanation:
This is not a Mathematical question, it's a fencing question. It just requires the knowledge of the fencing sport.
Knowing the rules of the game, would let one know that fencer X landed the first legal touch on the valid surface of fencer Y.
Fencer Y's touch on Fencer X's valid surface arrives when fencer X already tripped while retreating and fell.
QED!
Answer:
B if you mean log_7 (1)*log_ 5 (25)
Step-by-step explanation:
I think you mean 7 and 5 as bases... like
log_7(1)*log_5(25)
log_7(1)=0 because 7^0=1
log_5(25)=2 because 5^2=25
So you have to perform the following operation 0*2=0
so 0 is definitely one answer
1 and 5*7 are definitely not equal to 0
let's look at last choice now
log_7(7)=1 because 7^1=7
so D is equivalent to saying 2*1 which is 2 not 0
so only one choice works and it is B
