Given that a*b = ab-b/a
Evalute
1)-3+-4*8 is it 32-8/4=6?
2)2*(4*8) is the ans 64?
it means ab minus B divided by A
Well, then the * is an operator, so
1) -3+-4*8=-3+ -32-8/-4=-3-32+2=-33 as I see it.
I don't get either of your answers, but frankly, I am not certain of the function.
ab minus b divided by a could be
(ab-b)/a or ab - (b/a)
I get the same answers as Mr. Pursley:
If a*b = ab - b/a,
1)-3+-4*8 = -3 + (-4)*8 = 33
2)2*(4*8) = 2*(30) = 45
if a*b = (ab-b)/a,
1)-3+-4*8 = -3 + (-4)*8 = -3 + 10 = 7
2)2*(4*8) = 2*(6) = 3
To evaluate these expressions, we need to apply the given formula: a * b = ab - b/a.
1) -3 + (-4) * 8:
First, we calculate -4 * 8:
-4 * 8 = -32
Then, we substitute this result into the formula:
-3 + (-32) / (-3) = -3 + 32/3
To simplify further, we need to find a common denominator for the fraction:
-3 + (32/3)(-3/3) = -3 + (-96/3)
Next, we combine the integer and fraction:
-3 + (-96/3) = -3 + (-32)
Finally, we add the integers:
-3 + (-32) = -35
So, the answer is -35.
2) 2 * (4 * 8):
First, we calculate 4 * 8:
4 * 8 = 32
Then, we substitute this result into the formula:
2 * (32) - 32/2
Simplifying further:
2 * 32 - 32/2 = 64 - 16
Finally, subtracting:
64 - 16 = 48
So, the answer is 48.
