calculate: $(7^{2}-5^{3})+|8 - 12|×3$.
calculate: $(7^{2}-5^{3})+|8 - 12|×3$.
Answer
Explanation:
Step1: Calculate powers
$$ \begin{align*} 7^{2}&=49\ 5^{3}&=125 \end{align*} $$
Step2: Calculate the value inside the parentheses
$$(7^{2}-5^{3})=(49 - 125)=-76$$
Step3: Calculate the absolute - value
$$|8 - 12|=|-4| = 4$$
Step4: Calculate the multiplication
$$|8 - 12|\times3=4\times3 = 12$$
Step5: Calculate the final result
$$(7^{2}-5^{3})+|8 - 12|\times3=-76+12=-64$$
Answer:
(-64)
