Take the natural log of both sides
ln(2^x)=ln(.125)
Xln(2)=ln(.125)
X=ln(.125)/ln(2)
X=-3
ALTERNATIVE ROUTE:
You know that 0.125 is equal to 1/8
And 1/2^3 is also equal to 1/8
So since you need the reciprocal to match it the exponent is a negative
Answer:
square root 45 lies between 6 and 7
Step-by-step explanation:
I hope it's helpful!
value of x =-4 and value of y=-3
(-4,-3) is the solution of system of equations.
Step-by-step explanation:
We need to solve the system of equations

Rearranging:

Multiply eq(2) with 3 and subtract eq(2) from eq(1)

Putting value of x = -4 into eq(1)

So, value of x =-4 and value of y=-3
(-4,-3) is the solution of system of equations.
