Answer:
x=-13
Step-by-step explanation:
1. Divide both sides by -0.4
2. Subtract -3 on both sides.
3. -10-3=-13
Answer:
=-1648
Step-by-step explanation:
As it's a square root the underroot value must be greater than or equal to 0
So
let's find out the domain
- √4x+11≥0
- 4x+11≥0
- 4x≥-11
- x≥-11/4
Domain
1) Write the number in exponential form with a base of 10:
3√1000 = 3√10^3
2) Reduce the index of radical and exponent with 3:
3√10^3=10
