Question

Please solve this equation by simplifying

Answer 1

Answer:

Step-by-step explanation:

$\sqrt{82}=9.06$

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

Answer 2

Answer:

$10^2 \div 5 \times \sqrt{82} - \pi \times 2$

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

$10^2=10 \times 10=100$

$\implies 100 \div 5 \times \sqrt{82} - \pi \times 2$

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

$\implies 100 \div 5 \times \sqrt{82} - \pi \times 2$

$\implies 20\times \sqrt{82} - 2\pi$

$\implies 20\sqrt{82} - 2\pi$

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

$20\sqrt{82} - 2\pi=1.748245175...$
