Question6) $\left(7 \times 5+6^{2}\right)+2$ 7) $\left(86-6^{2}\right)+(-1+3)$ 8) $(35-5)+2+2^{2}$ 9) $(2+2)^{2}+(10+5)$ 10) $\left(61-5^{2}\right) \div(8+4)$

Studdy Solution
Evaluate expression 10: $\left(61-5^{2}\right) \div(8+4)$.
1. Calculate the exponent: $5^{2} = 25$.
2. Subtract inside the parentheses: $61 - 25 = 36$.
3. Add inside the parentheses: $8 + 4 = 12$.
4. Divide the results: $36 \div 12 = 3$.
The result of expression 10 is $\boxed{3}$.
