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
