additoin of exponentials

Topic:- exponentials

Let's see what is exponent first, generally

BaseExponent

The exponent tells us how many times the base is used as a factor.

For example, to write 2 as a factor one million times, the base is 2, and the exponent is 1,000,000. We write this number in exponential form as follows:

2

1,000,000

read as two raised to the millionth power

This math help gives a example problem on addition of exponents.

Question:-

-3 z6(b3y2z2)

Answer:-

-3 z6(b3y2z2)
                   
Here we have 'z' for twice ,
So we can put them as 1 term by
additing the exponentials

we can add them by using exponent rule

formula of exponent

    am * a n = a m+n
So,
    -3 (z6+2*b3*y2)

    -3 (z8*b3*y2)

      -3z6+2*b3*y2 is the Answer

Topic:Probability

Probability, is a way of expressing knowledge or belief that an event will occur or has occurred.

Here is some probability problems ,which help you to understand the concept much better.

Questions & Answers

1- Mr. Johnson taught a music class for 25 students under the age of ten. He randomlychose one of them. What was the probability that the student was under twelve?

Ans:-

The probability that the student was under twelve was 25/25, so P = 1.

2- The compact disk Jane bought had 12 songs. The first four were rock music. Tracks
number 5 through 12 were ballads. She selected the random function in her Compact
Disk Player. What is the probability of first listening to a balla?

Ans:-

The probability of listening to a ballad is 8/12, so P = 0.67.
