30(-2/5)²(5/8) = 30*(4/25)*(5/8) = 30*4/(5*8) = 3
The exponent symbol when typing is ^. so I so rewrite this for you.
(15x^8 / 24y^5) / (4x^4 / 8y^2)
I assumed you meant 8y squared because you said 8 squared.
now when we divide by a fraction, we can actually multiply by it's reciprocal and get the same thing. The word reciprocal really just means flip it over. so:
(15x^8 / 24y^5) * (8y^2 / 4x^4)
let's reduce the coefficients ( the numbers in front of the x and y) to make it easier.
We have 15/24 which can be reduced to 5/8
and 8/4 which is 2/1
so:
(5x^8 / 8y^5) * (2y^2 / x^4)
multiply numerator and denominator
(10x^8y^2) / (8x^4y^5)
now reduce coeffient. 10/8 is 5/4
reduce x: x^8/x^4 is x^4
reduce y: y^2/y^5 is 1/y^3
now put together
5x^4 / 4y^3
so C
Answer: D.
Step-by-step explanation: You can't have 2 y of the same y axis numbers in a function and A isn't correct because it doesn't go in order.
Answer:
Yes because 20 percent of anything, including 0, multiplied by 5 is 100 percent
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Standard form is in number form.
For example, the standard form of 12+6 is 18
We need to solve 90,000 + 700,000 + 40,000,000 + 100,000,000 to get the standard form.
The standard form is 140,790,000. So the answer is D.
Hope this helps :)
Have a great day!
