Write the expression as a single logarithm

Mathematics
1 answer:
viva [34]3 years ago
5 0

We have to use the following log rules here

a log (b) = log b^a  , log(a) + log(b) = log(ab), log (a)-log(b) = log(a/b)

So for the given question , that is

18log \sqrt x +9 log \sqrt [3]{x}-log 10 = log(x^{18/2}) + log(x^{9/3})-log 10

log(x^9)+log(x^3)-log 10= log(x^9*x^3)-log 10

=log(x^{12}) - log 10 = log(\frac{x^{12}}{10})

Solve the following quadratic equation<br>x+12x+36 - 16​
Doss [256]

Answer:

x= -2, x= -10

Step-by-step explanation:

x^2 + 12x + 36 = 16

Began by setting this quadratic equation to 0. To do this, in this equation you must subtract.

x^2+12x+20=0

Next, we plug this into the quadratic formula, where a in this case is 1(there is nothing in front of x^2), b is equaled to 12(there is a 12 as the coeefficient of 12x), and c is equaled to 20.

The quadratic formula is as goes:

(-b+-(this means plus or minus)√b^2-4ac)/(2a)

After pluggin in and simplifying, the answer is x= -2 and x= -10

If you know the 7x8=56 how can you use the Commutative Property of Multiplication to find the product of 8x7?
boyakko [2]

Answer:

The communicative property for multiplication states that the order of the multiplicands and can be swapped and the resulting product stays the same.

So

A * B = B * A

So if

7*8=56

then the commutative property says

8*7=56 as well since you can swap the order of the terms on the left and not change the result.

This property is true for addition and multiplication. It does not hold for subtraction or division.

Hope that makes sense and helps. (:
