Question

A) penyelesaian PERtidaksamaan linear : 3x - 7 > 5 =
b)jika ⁷log 2 = a dan ²log 3 = b, maka ⁶log 14 =

tolong ya,penting

Answer 1

3x -7>5
3x>5+7
3x>12
x>4

hp: { x| x>4} . hp: {5,6,7....}

Answer 2

A. 3x-7>5
3x>12
x>4

b. 6log 14 = 6log 2 + 6log 7
=(2log 2 + 2log 3)^(-1) + (7log 2 + 7log 3)^(-1)
= (1+b)^(-1) + (a+ab)^(-1)
= (a+1)/(a(b+1))
