Question

(2³)-1×2⁴+10+10‐¹+5²:5​

Answer 1

$(2^3) - 1 * 2^4+10+10^{-1}+5^2:5 = 8-1*16+10+\dfrac{1}{10}+5 = 8 - 16+10+\dfrac{1}{10}+5= 7+\dfrac{1}{10}= \dfrac{71}{10} = 7,1$

Answer 2

Let's solve the expression step by step:

1. Calculate $2³$ which is $2 \times 2 \times 2 = 8$.
2. Calculate $2⁴$ which is $2 \times 2 \times 2 \times 2 = 16$.
3. Calculate $10-¹$ which is $1/10 = 0.1$.
4. Calculate $5²$ which is $5 \times 5 = 25$.
5. Divide $25$ by $5$, which gives $25/5 = 5$.

Now, plug the calculated values back into the expression:

$(2³) - 1 \times (2⁴) + 10 + 10-¹ + 5²:5$ $= 8 - 1 \times 16 + 10 + 0.1 + 5$ $= 8 - 16 + 10 + 0.1 + 5$ $= 7.1$

So, the value of the expression is $7.1$.
