What is the value of the expression? 80 +
3
4 - 6 • 5
a. 62
b. 114
c. 430
d. 690

The correct answer is B: 114

Step-by-step explanation:

80 + 4^3 - 6 * 5

Using pemdas there are no parenthesis so you must start with exponents.

4^3 = 4 * 4 * 4 = 64

80 + 64 - 6 * 5

Next following pemdas you do multiplication or division. (Which ever comes first in the problem)

6 * 5 = 30

80 + 64 - 30

Finally, following pemdas is addition or subtraction. (Again which ever comes first in the problem)

Since 80 + 64 comes first start with that.

80 + 64 = 144

What's left is 144 - 30

144 - 30 is 114

So your answer is B. 114

correct answer:

i^31 = -i
