<span>loga (2) = 0.3812
</span><span>loga (3) = 0.6013
</span><span>loga (5) = 0.9004
</span><span>and we should know that loga a = 1
</span>
∴ loga (30a)³ = 3 loga (30a) = 3 loga (2 * 3 * 5 * a) = 3 ( loga 2 + loga 3 + loga 5 + loga a ) = 3 ( <span>0.3812 + 0.6013 + 0.9004 + 1 )
</span> = 3 * 2.8829 = 8.6487
The correct answer is option <span>C. 8.6487</span>
9x^2 + 24 x + 16 = 0
(3x +4) (3x + 4) = 0
x=-4/3
are you sure part A doesn't have a negative somewhere?
9x^2+12x+12x+16 this works just double checking
b)
16x^2 - 25y^2 = 0
(4x-5y)(4x+5y)= 0
hope this helps
It's would be plus haft that number (it's a negative) and the next number would be 0
Might be wrong haven't done algebra for years but i think it is 7-9n/7
