ANSWER
EXPLANATION
First we can take the root out of the argument of the logarithm. Remember that roots can be written as fractional exponents:
So applying the power rule of logarithms:
Next we can apply the quotient rule of logarithms:
Then we use the product rule for the last term:
And the power rule for the exponent of c:
What we have to do now is rewrite this to be more clear. Apply the distributive property for the minus sign into the expression with the logarithms of b and c:
And then do the same for the 1/4 coefficient:
In summary:
Answer:
-9, -15 is the answer for the extra two
Answer:
-4
Step-by-step explanation:
2x + 5 = 85
2x = 80
x = 40
3x/(10-x)
3(40)/(10-40)
120/-30 = -4
Answer:
7.22
Step-by-step explanation:
11.2 minus 3.98
1/5 is reduced to .2
hope this helps
40(11.28)+6(11.28*1.5)
40(11.28)+6(16.92)
451.2+101.52
$552.72
