Answer:
● 
Step-by-step explanation:
According to the Definition of Rational Exponents [part I], you can rewrite radicals as exponents:
![\displaystyle a^{\frac{m}{n}} = \sqrt[n]{a}^m \\ \\ \sqrt{y^2} = y, where\:any\:invisible\:exponent\:is\:ALWAYS\:1](https://tex.z-dn.net/?f=%5Cdisplaystyle%20a%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D%20%3D%20%5Csqrt%5Bn%5D%7Ba%7D%5Em%20%5C%5C%20%5C%5C%20%5Csqrt%7By%5E2%7D%20%3D%20y%2C%20where%5C%3Aany%5C%3Ainvisible%5C%3Aexponent%5C%3Ais%5C%3AALWAYS%5C%3A1)

The answer would be 1 were to estimate
During the birthday 4/7 of the cake was eaten so it remained 1-4/7=3/7
the next day 1/2 of 3/7 was eaten what remained is 3/7 divide by 1/2
to divide we invert the second fraction (1/2) and multiply 3/7
3/7 x 2/1=6/7
Answer:
(2,2)
Step-by-step explanation:
Given equations are
x+3y=8 eq(1)
2x-y=2 eq(2)
we'll solve the system of equation by substitution.
Adding -3y to both sides of eq(1),we get
x+3y-3y=8-3y
x+0=8-3y
x=8-3y eq(3)
Put above value of x in eq(2),we get
2(8-3y)-y=2
16-6y-y=2
16-7y=2
Adding -16 to both sides of above equation,we get
-16+16-7y=-16+2
0-7y=-14
-7y=-14
Dividing by -7 to both sides of above equation,we get
-7y/-7=-14/-7
y=2
Putting y=2 in eq(3),we get
x=8-3(2)
x=8-6
x=2
hence, the solution for this system of equations is (2,2).
