Answer: $\frac{1}{b^6}$ or $b^{-6}$

Step-by-step explanation:

$\frac{b^-2+2}{b^4+2}$ Add the exponent two to both sides. After adding -2 and 2 you get 0 and any number raised to the zero power is one. And 4 plus two is 6

$\frac{b^0}{b^6}$ = $\frac{1}{b^6}$

Jo is thinking of a number. Four less than 9 times the number is 176. Find Jo’s number

kondaur [170]

Answer:

Jo's Number is 20.

Step-by-step explanation:

4 - ( 9 x ? ) = 176.

9 x 20 = 180.

9 x 20 = 180, then subtract 180 by 4.

180 - 4 = 176.

Factor the binomial expansion. 81x4 – 648x3 + 1,944x2 – 2,592x + 1,296

scoray [572]

Answer:

$648$ ( $x^{3} + 3x^{2} - 4x + 2$ )

Step-by-step explanation:

When factoring an expression like this, you need to divide all of the parts by a common number or variable. In this case, the only thing all of these numbers share is that they are divisible by 648. So, you would divide each number by 648 to simplify it, getting 1, 3, 4, and 2. Put these numbers in front of their respective variables, and put 648 outside of the parentheses to get the final answer.
