Question

what's the awnser to 1/2(4×5)- 2³=

Answer 1

Answer:

2

Explanation:

To simplify the expression we use PEMDAS.

$\frac{1}{2}(4\cdot5)-2^3$

first we evaluate he parenthesis to get

$\frac{1}{2}\cdot20-2^3$

then the exponents

$\frac{1}{2}\cdot20-8$

then multiplication

$10-8$

and finally, the subtraction

$10-8=2$

Hence,

$\frac{1}{2}(4\cdot5)-2^3=2$

which is our answer!
