Add. what is the sum (2 x 10") + (7 x 1016) in scientific notation? plz

9 x 10¹⁶.

To sum two numbers in scientific notation  it must be taken into account that the power of 10 has the same number and the numbers are normally added and the power of 10 is maintained.

a x 10ⁿ + b x 10ⁿ = (a + b) x 10ⁿ

Then, sum the numbers shown in the image:

(2 x 10¹⁶) + (7 x 10¹⁶) = (2 + 7) x 10¹⁶ = 9 x 10¹⁶

9 times 10^16

Explanation:

when adding or subtracting in standard form (aka scientific notation), the powers of  

10

 need to be the same. If they are just add the numbers and keep the same power of  

10

#2xx10^(16)+7xx10^(16)

= ( 2 + 7 ) × 10 ^16

=9 × 10 ^16

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
