Answer:
Number 2: -3/10 (I think)
Number 4: 10a-5b-4
Number 6: x=5/2
Number 8: x=6
Step-by-step explanation:
Number 2:
3ysquared/2y-4x2
3(-1)squared/2(-1)-4x2
3x1/2(-1)-4x2
3x1/-10
-3/10
(I might be wrong with this one though)
Number 4:
10a-3b-4-2b
10a-5b-4
Number 6:
2(-3x+8)=4x-9
-6x+16=4x-9
-6x+16-16=4x-9-16
-6x=4x-25
-6x-4x=4x-25-4x
-10x=-25
-10x/-10=-25/-10
x=5/2
Number 8:
1(4x-8)/4=-x+10
4x-8/4=-x+10
4x-8/4+x=-x+10+x
8x-8/4=10
4x8x-8/4=4x10
8x-8=4x10
8x-8=40
8x-8+8=40+8
8x=48
8x/8=48/8
x=6

4 because 23.63 rounds up to 24, then divide 6 by 24, or 24 by 6
Answer:
Radical form of the expression
is, 8
Step-by-step explanation:
Given the expression: ![4^{\frac{3}{2} }](https://tex.z-dn.net/?f=4%5E%7B%5Cfrac%7B3%7D%7B2%7D%20%7D)
Since,
is same as ![4^{\frac{3}{2} }](https://tex.z-dn.net/?f=4%5E%7B%5Cfrac%7B3%7D%7B2%7D%20%7D)
Now, to write an exponent in radical form,
then the denominator or the index goes in front of the radical and
the numerator goes inside of the radical.
we raise the base to the power of the numerator then:
=
=
= ![\sqrt{8^2} = 8](https://tex.z-dn.net/?f=%5Csqrt%7B8%5E2%7D%20%3D%208)
therefore, the radical form of the given expression is, 8
