The simplified form of the expression. give your answer in scientific notation. (8 x 10 to the 7th power) ( 7 x 10 to the 4th power)

a: 1.5 x 10 to the 12th power,
b: 5.6 x 10 to the 12th power.
c: 1.5 x 10 to the 29th power.
d: 5.6 x 10 to the 29th power.

B: 5.6 x 10 to the 12th power.

Step-by-step explanation:

8* 10^7  * 7* 10^4

Multiply the first terms and add the powers of 10

56 * 10 ^(7+4)

56. * 10 ^11

This is not proper scientific notation

We can only have one number in front of the decimal.  We have to move the decimal one place to the left, which means we add one to the exponent

5.6  * 10^ (11+1)

5.6  * 10^12

step-by-step explanation:

first, eliminate the parenthesis:

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x
