Step-by-step explanation:

Difference of Squares: a² - b² = (a + b)(a - b)

(x² - 16) / (x - 4)

= [(x + 4)(x - 4)] / (x - 4)

= x + 4, where x =/= 4.

Why is this number not in scientific<br> notation?<br> 36.5 x 10^6<br> please help
andrew11 [14]

Answer:

The first number should be a number between 1 and 10 (see explanation)

Step-by-step explanation:

For a number to be in scientific notation, a number between 1 and 10 has to be multiplied by a power of 10.

36.5 is not between 1 and 10, alternatively, you can rearrange it:

3.65 x 10^7      <----This would be the correct scientific notation

What is 9.36•10~4 in standard form
marta [7]
With exponents of 10, the exponent really just tells you how many zeroes there are behind the 1. So, for example, 10^4=10000 (4 zeroes behind 1). When multiplying decimals by exponents of 10, you move the decimal to the right, and the amount of places is the exponent number. For example, if I multiply 5.34 by 10^2, I move the decimal over to the right 2 times and get 534.

So, if you just multiply these you get 9.36*10000, which is 93600.
