Answer 1

The answer to your question is -3/8

Answer 2

Negative three eighths.

Explanation:

Our given expression is
`1/2^(3) - 4` ÷
`√(64)`

To simplify (or, solve), use

P parenthesis

E exponents

M multiplication

D division

A addition

S subtraction

We see first that there are no parenthesis. Skip this part.

Next up is exponents. 1/2 cubed is 0.125, or 1/8.

We see now that there is no multiplication. Skip this part.

Now, we do division. -4 ÷
`√(64)` = -1/2.

No addition is in this expression. Skip this part.

Finally, we subtract. We are left with 1/8 - 1/2 = -0.375, or -3/8.
