Step-by-step explanation:
the equation of a circle centred at the origin is
x² + y² = r² ( r is the radius )
(11)
- 81 + x² = - y² ( add y² to both sides )
- 81 + x² + y² = 0 ( add 81 to both sides )
x² + y² = 81 ← in standard form
with centre = (0, 0 ) and r = = 9
(12)
y² + x² - 196 = 0 ( add 196 to both sides )
x² + y² = 196 ← in standard form
with centre = (0, 0 ) and r = = 14
Answer:
2 is inside the radical.
Step-by-step explanation:
We have to write the radical expression in simplest form
Let us find the factors of 1250
Hence, we can rewrite the radical expression as
Using the exponent rule
Hence, we have 2 is inside the radical.
