What is Logarithm?
In mathematics, Logarithms are defined a way of expressing exponents. A logarithm is defined as the power to which a number must be raised to get some other values.
The expression for logarithm of a number is written as ㏒ₓb = y.
Properties of Logarithm:
The value of can be calculated by recognizing that
is equal to 2 raised to the power of -3.

To find the value of f(-3), put -3 in place of 'x' in the definition of the function.
f(-3) = -8(-3)²
f(-3) = -8(9) = -72
f(-3)= -8* (-3)²
f(-3)= -8 * 9
f(-3)= -72

When writing an equation in slope-intercept form, there will be need for slope and y- intercept.
What is the slope intercept form of an equation ?
When any equation is represented in the y = mx +c form, it is called the slope intercept form of the equation.
Here m is slope and c is constant.
To writing the slope intercept form of the equation,
There will be requirement of slope,
and y intercept, it will be in form of (0, a), here a will be value of y coordinate.

Answer:
72
Step-by-step explanation:
First, divide 32 by 4 to see how many times larger the numbers in the second ratio are than in the first ratio. 32/4=8 This means that the numbers in the second ratio are 8 times larger than in the first
Then, since the second ratio’s numbers are 8 times bigger than those of the first ratio, you can multiply both numbers in the first ratio by 8. The problem already multiplied 4 by 8 for us, which is 32, so all we have to do now is multiply 9 by 8. 9*8=72, which means that 4:9 is equivalent to 32:72

Factor by grouping: 6x2 + 3x + 20x + 10.
This is a polynomial written with four terms that don't have a single common factor among them. However, the first two terms have a common factor (3x), and the last two terms have a common factor (10). This situation doesn't answer all of our wildest factoring dreams, but we'll take it.
By pulling out the common factors for each pair of terms, we can rewrite the original polynomial like this:
3x(2x + 1) + 10(2x + 1)
These two terms now have a common factor of (2x + 1). Seems like we should be able to do something with that information, don't you think? In fact, we can pull out this common factor and rewrite the polynomial again:
(3x + 10)(2x + 1)
Step 1: Determine the greatest common factor of the given terms. The greatest common factor or GCF is the largest factor that all terms have in common.
Step 2: Factor out (or divide out) the greatest common factor from each term.
Step 1: Determine the greatest common factor of the given terms. The greatest common factor or GCF is the largest factor that all terms have in common.
