To make sure you do this correctly, first i would suggest separating the 3 and the x
3•x^3/8
For a fractional exponent, the denominator is the root you take of the number (in this case the eight root) and the numerator is the exponent of the number under the radical.
3• ^8√x^3
Sorry that's a little messy, it's the best i can do on my phone!!
The multiplication symbol ( • ) is not necessary, I just put it there to make things more clear.
Hope this helps!
The area of a circle is given by

We can solve this equation for r: divide both sides by pi:

Consider the (positive) square root of both sides:

So, in your case, we have

Answer:
Step-by-step explanation:
Question 3
5 (k + 4) - 2k
Use distributive property of multiplication.
5k + 20 -2k
Combine like terms to get your answer.
3k +20
Question 4
2 (3 + d - 1)
Simplify the expression in the parenthesis.
2 (2 + d)
Use distributive property of multiplication.
4 + 2d
If you wanted it to be accepted at higher levels, switch the terms around.
2d + 4
550-500 is not 500 it’s 50
This is true. It would only be incorrect if dilations were there, because dilations don’t keep the shapes congruent.
