For the first one (10C4) it is 5040 and the second one (6P4) is 360. Hope that gives you a boost on answering! :D (sorry for the pink lighting) XD
PS. "10! = 1x2x3x4x5x6x7x8x9x10 or 10x9x8x7x6x5x4x3x2x1" "6!= 1x2x3x4x5x6 or 6x5x4x3x2x1"
They are both equivalent to 1/2
Answer:
3 (8v+5) (8v-5)
Step-by-step explanation:
192v^2 -75
factor out a 3
3 (64v^2 -25)
now the inside is a difference of squares)
a^2 – b^2 = (a + b)(a – b) where a = 8v and b =5
3 (8v+5) (8v-5)
<u>Answer:</u>
log7
<u>Step-by-step explanation:</u>
We are given the following expression in terms of log and we are to solve it:
log (14/3) + log (11/5) - log (22/15)
Just to recall, when we divide two values that have the same base, we basically subtract the exponents.
So applying this rule here to get:
(log11 - log5) + (log14 - log3) - (log22 - log15)
= log11 - log5 + log14 - log3 - log2×11 + log5.3
= loh11 - log5 + log14 - log3 - log2 - log11 + log5 + log3
Cancelling out the like terms to get:
= log14 - log2
= log 14/2
= log7
