Express in scientific notation 417.8

4.178  times  10  to the power 2

Explanation:

Scientific notation has one number before the decimal place. This can be moved by figuring out how many places the decimal needs to move. Since this problem calls for it to move 2 places to the left, the exponent is 2.

the answer is 62

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
