Answer:
The correct option is 1/4^2
Step-by-step explanation:
The given expression is:
4^6 * 4^-8
According to the same base rule if the exponents have the same base then the exponents will be added.
If we look at the given expression both the values have the same base.
Therefore we will add the exponents of the value.
= 4^6+(-8)
= 4^6-8
= 4^-2
Now to change the negative exponent into positive we will take it to the denominator.
4^-2 = 1/4^2
Thus the correct option is A....

Answer:
x,y =2,1
Step-by-step explanation:
3x+4y=10 ................equ1
x-y=1 ................equ2
This system of equations forms a quadratic equation.
Lets use the substitution method in solving this set of equations
from equ 2; x=y+1
substitute x=y+1 into equ 1
3(y+1) +4y=10
3y+3+4y=10
7y=10-3
7y=7
y=7/7
y=1
but x=y+1
substitute the value of y into this equation to get x
x= 1+1
x=2
x,y=2,1
