Answer:


10^2 / 5 * √(82) - \pi * 2

Using order of operations, we need to carry out the exponents first:


10^2=10 * 10=100


\implies 100 / 5 * √(82) - \pi * 2

Then we need to carry out multiplication and division (it doesn't matter in which order):


\implies 100 / 5 * √(82) - \pi * 2


\implies 20* √(82) - 2\pi


\implies 20√(82) - 2\pi

Unless you have been given an approximation for pi, it cannot be simplified any further.


20√(82) - 2\pi=1.748245175...

Answer:

Explanation:


√(82)=9.06

10² ÷ 5 *√82 - π*2 = 100÷ 5 *9.06 - 3.14*2

= 20 *9.06 - 3.14*2

= 181.2 - 6.28

= 174.92

or

10² ÷5 *√82 - π*2 = 100÷5 *√82 - 2π

= 20√82-2π
