Question

What is the value of the expression shown below?3+ (2 + 8)2 = 4

Answer 1

Solve the equation:

`3+((2+8)^2)/(4)*((1)/(2))^4`

There is an order for the operations we do, and the first thing we should check is for the existence of parentheses or brackets, then we do the exponencials and roots, then the multiplications and divisions, and then the sum. Following this order, I'm going to write the steps for this equation:

`3+\frac{(2+8)^2}{4^{}}*((1)/(2))^4=3+\frac{10^2}{4^{}}*(1)/(2^4)=3+(100)/(4)*(1)/(16)`
`=3+25*(1)/(16)=3+(25)/(16)=3+(9+16)/(16)=4+(9)/(16)`

And this is our solution. 4 9/16
