a=9 b=2 c=5 d=3
2ab to the second power - cd =
i got 1,281
Right.
Could be a problem here ....
The way you said it according to the order of operation :
2ab^2 - cd
= 2(9)(2^2) - 5(3)
= 72 - 15
= 57
The way it was interpreted:
(2ab)^2 - cd
= (2(9)(2))^2 - 5(3)
= 36^2 - 15
= 1281
To find the value of the expression 2ab^2 - cd, we need to substitute the given values of a, b, c, and d.
Given:
a = 9
b = 2
c = 5
d = 3
Substituting these values into the expression, we get:
2ab^2 - cd = 2 * (9) * (2^2) - (5) * (3)
First, we need to evaluate the exponent 2^2, which equals 4:
= 2 * 9 * 4 - 5 * 3
Next, we perform the multiplications:
= 72 - 15
Finally, we subtract:
= 57
So, 2ab^2 - cd = 57.
