Find the value of the expression.
y3 + x
for x = 6 and y = 1

9

To solve this, you'd first have to substitute the values of x and y. Since x=6 and y=1, all you have to do is plug them in.

Equation:  (1)3+6

Next, all you have to do is solve. Since 3(1)=3, and 6+3=9, the value of the expression is equal to 9.

**Unless the 3 is an exponent. It didn't look like it to me but I solved that as well just in case***

Equation: y³+x

1. Substitute

(1)³+6

2. Solve

1³= 1 and 1+6=7

So, the answer is 7 (again, this is only if the 3 is an exponent. I couldn't tell)...

Hope this helps,

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)

step-by-step explanation:

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
