Find the simplified form of each expression. give your answer in scientific notation.
(5 x 10^-7) (8 x 10^-4)

a) 4 x 10^13
b)4 x 10^-12
c)40 x 10^-10
d)4 x 10^-10

D)4 x 10^-10

Step-by-step explanation:

The given expression is

(5 x 10^-7) (8 x 10^-4)

Firstly, we would multiply the numbers on the left hand side of the 10. It becomes 5 × 8 = 40

Multiplying the 10's, we would apply the law of indices to the powers of 10. It is expressed as

a^2 × a^3 = a^(2 + 3) = a^6

Therefore,

10^-7 × 10^-4 = 10^(- 7 - 4) = 10^ - 11

The simplified form of each expression in scientific notation would be

40 × 10^ -11

= 4 × 10^ -11 +1

= 4 × 10^ -10

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.

first, let's see what the pattern is.

58 - x = 47

46 - x = 36

x = 9

so this means that the term after 25 is 25 - 9:

the next term in the sequence is 16.
