What is the value of the missing exponent?
123,456,789 = 1.23456789 x 10^

Step-by-step explanation:

It is required to find the value of the missing exponent in the below value i.e.

Let the exponent is x.

Any number can be written in the scientific notation as :

a is a real number

b is any integer

In this case, the decimal is applied before 8 numbers. It means that the value of x is 8.

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
