I think it’s 90% cuz it’s 45/50 therefore 90/100
1) (m³n⁵)(mn⁴)
-----------------
m⁻³n²
Simplify.
m⁴n⁹
-------
m⁻³n²
When the bottom power is a negative, you add it to the power on top, & when the power is a positive, you subtract it.
m⁴ + m³ = m⁷
n⁹ - n² = n⁷
So, our answer for #1 is m⁷n⁷
2) 6a²b³
---------
4a
Please read rules in #1.
6 / 4 = 3/2 & a² - a = a
So, our answer is 3a
-----
2
3) 5⁶a⁶b³
---------
5²ab³
5⁶ - 5² = 5⁴ AND a⁶ - a = a⁵ AND b³-b³ = 0
So, our answer is 5⁴a⁵
Simplify 5⁴
5 × 5 × 5 × 5 = 625
So, our final answer is :
625a⁵
~Hope I helped!~
X^2/(x- 9 = 81/(x - 9)
This is the equation for which you want the solution.
Multiplying both sides of the equation by (x - 9) we get
x^2(x - 9)/(x - 9) = 81(x - 9)/(x - 9)
So the (x - 9) goes out from both the denominator and the numerator and then the simplified equation becomes
x^2 = 81
x ^2 = (9)^2
x = 9
So the value of the unknown variable x comes out to be 9.
The power of two is any number squared.
Example~ 3*3, 5*5, 8*8
