Answer:
a) 1.59967 * 10 ^-12
b) 7.52711497
c) 1.590778098 * 10^-1
Step-by-step explanation:
a= 3.47 x 10^-6,
b=4.61 x 10^-7,
c=5.52 x 10^-7
a) a*b = 3.47 x 10^-6* 4.61 x 10^-7
We multiply the numbers out front and add the exponents
(3.47*4.61) * 10^(-6+-7)
15.9967 * 10^-13
But this is not correct scientific notation, we need 1 number in front of the decimal. Move the decimal 1 place to the left and add 1 to the exponent
1.59967 * 10^(-13+1)
1.59967 * 10 ^-12
b) a/b = 3.47 x 10^-6/ 4.61 x 10^-7
We divide the numbers out front and subtract the exponents
(3.47/4.61) * 10^(-6- -7)
(3.47/4.61) * 10^(-6+7)
.752711497* 10^1
But this is not correct scientific notation, we need 1 number in front of the decimal. Move the decimal 1 place to the right and subtract 1 from the exponent
7.52711497* 10^1-1
7.52711497
c) c/a = 5.52 x 10^-7/3.47 x 10^-6
We divide the numbers out front and subtract the exponents
(5.52/3.47) * 10^(-7- -6)
(5.52/3.47) * 10^(-7+6)
1.590778098 * 10^-1
Constants values in the expression 2x+3y+4z+5a+6b are 2,3,4 ,5 and 6.
A constant is a value or number that is consistently the same regardless of how it is expressed. For instance, in the aforementioned figure, where its face value is 36 and 82 respectively, 36 and 82 remain constant. Its worth remains constant.
To broaden our definition, we can say that a constant is something that never changes. Either a single digit or a symbol that denotes a specific number is used. You could substitute a letter like a, b, or c for a constant.
An illustration of a constant term is the mathematical symbol Pi. The word "Pi" refers to a well-known number that can be used alone.
