Answer:
The correct answer is option c
7
Step-by-step explanation:
<u>Points to remember</u>
Log(x^a) = a log x
log 10 = 1 [since the base is 10]
It is given that, correct answer is option c
log(10^7)
<u>To find the correct option</u>
By using logarithmic identities we can write,
log(10^7) = 7 log 10
= 7 * 1 [ since log 10 = 1]
= 7
Therefore the correct answer is option c
B. 30
3x + 2x + x = 180 (angle sum of a triangle is 180)
6x = 180
x = 30
#3 is 40
#4 is 90
x = 35
Since m1=m2 :
-2 x 3/7 = (-2 x 3) /7
= -6/7
