It looks like goulash.
Try this sqrt. As in sqrt(x*34)
I use alt251 on kbd and I see the sqrt symbol but it doesnt view that way...
1.
-sqrt18c - sqrt-2c(cubed)
2.
isqrt-98 - sqrt98
To simplify expressions, we need to perform the indicated operations and combine like terms, if any.
Let's simplify the given expressions step by step:
Expression 1: 54 - 18c * (-2c^3)
1. Start by simplifying the multiplication part.
Multiply -18c by -2c^3:
(-18c) * (-2c^3) = (-18) * (-2) * c * c^3
= 36c^4
So, the expression becomes:
54 - 36c^4
Expression 2: y√(-16y^2) + √(16y^2) - y^2√(-9)
1. Simplify the square roots.
The square root of -16y^2 is not defined in the real number system because it involves an imaginary part.
However, we can simplify it using the concept of imaginary numbers and "i".
The square root of -16 can be written as 4i, and the square root of y^2 is y.
Therefore, the expression becomes:
y * 4i + 4y - y^2 * √(-9)
2. Simplify the multiplication part.
Multiply y * 4i:
y * 4i = 4iy
3. Simplify the square root of -9.
The square root of -9 can also be written as 3i.
Therefore, the expression becomes:
4iy + 4y - y^2 * 3i
Finally, combine like terms if any.
In this case, there are no like terms to combine.
So, the simplified expression is:
4iy + 4y - 3iy * y^2
