Question

Assume that the notation (o, p, q, r) means " Multiply o and p. Subtract q from the product, and then raise to the power of r, " What is the value of (8, 2, 16, 3) + (7, 7, 39, 2)?

Answer 1

The equation would be [(8x2)-16]^3 for the first one.

Answer 2

Explain?

Answer 3

(o, p, q, r)

turns into the expression

(o*p-q)^r

based on the instructions given

Answer 4

This is similar to the questions that use a made up operation. They're making up a notation and telling you what that notation means. The answers above pretty much explained it. It's saying, if you have four values in parenthesis like that, you multiply the first two, subtract the third, and then raise to the power of the fourth.

Answer 5

((o * p)-q)^r Jim.... right?

Answer 6

correct Jhannybean

Answer 7

So we substitute the values of o, p, q, and r into the expression.

Answer 8

yes

Answer 9

Sorry for the delay. Yes, we substitute the numbers by he rules of the way that the alphabets are lined up.

Answer 10

I see... So the equation would be: [(8 * 2)-16]^3 + [(7 * 7) - 16 39]^2 ?

Answer 11

For the second one it would be

[(7x7)-39]^2

Answer 12

Sorry there was supposed to be a parenthesis after the 39.

Answer 13

Yes you are right. Then you use PEMDAS to evaluate the expression.

Answer 14

[(7 * 7) - 39]^2 *

Answer 15

That would equal to 100.

Answer 16

49-39= 10. Then 10x10=100

Answer 17

[(8 * 2)-16]^3 + [(7 * 7) - 39]^2

(16 - 16)^3 + [(49)-39]^2
(0)^3 + (10)^2

0 + 100 = 100

Answer 18

So the answer is 100

Answer 19

Good job @GoldPhenoix

Answer 20

Ah, I see. This take some time to answer this question.

Answer 21

Toughest part, who do I give the medal to...
