(1) ERROR IN THE SIMPLIFICATION:
Order of radicals are not made equal
(2) CORRECT SOLUTION:
Answer:
-4
Step-by-step explanation:
Part A
We know that √x = 3
Squaring both sides
x = 3²
⇒ x = 9
Hence, the value of x or the minimum value of x is 9
Part B
(*y²) ÷ (0.4*) = (*y²) *
⇒ (*y²) ÷ (0.4*) = *yx
Answer:
X = 2
Step-by-step explanation:
4-14=5x
10=5x
10/5=5x/5
2=x
The answer to this is -76
