In order to rewrite an expression in radical form using exponents, we must consider the power of the root (is the radical the typical square root, cubed root, etc) and the value of any exponents contained in the radical.
Using this information, we will make the power of the radical the denominator of our exponent, and whatever exponent is contained in the radical will become the numerator.
Example:
√(x³) = square root of x³ = x^(3/2)
Plz mark me brainliest if it was useful for you !!!
Ans is 86 - 14x
Steps in image :-
Michael is x. Michelle is y.
x+y=27
x-5=y
Substitute y
x+(x-5)= 27
2x-5=27
2x=32
x=16
Plug in x value
(16)+y=27
y=11
Final answer: Michael-16, Michelle-11
The answer is A, because:
3^8x(3^11)^-3
3^8x3^-33
1/3^25
Answer:
This system has one solution only
Step-by-step explanation:
We have to evaluate the equations shown in the picture you gave
Since the equations differs, they are not the same, this system has only on solution for x and for y.
In fact, if we sum them, we obtain y=0, and then x=2
