Answer:
Step-by-step explanation:
y²-x⁴
y=9, x=2
9²-2⁴ = 81-16 = 65
Answer:
1617/38.5 = 42
Step-by-step explanation:
Figure out what divisor you want, multiply that by 42 to find the dividend, then write your equation as ...
dividend/divisor = 42
So first step is to simplify everything outside of the radicals.
6*2=12
:. The expression is
__ __
12*\| 8 * \| 2
Now we know that
__ __ __
\| 8 = \| 4 * \| 2
And
__ __
\| 2 * \| 2 = 2
And
__
\| 4 = 2
So if we incorporate what we know into the equation, we can figure it out.
So let's first expand the radical 8.
__ __ __
12*\| 4 * \| 2 * \| 2
Now by simplifying the radical four and combining the radical twos, we can get all whole numbers.
12*2*2
Which equals 48.
Answer:48
