Question

68 - 15(1 - 5)² + 2³

Explanation:

Step1: Solve inner parentheses

$1-5 = -4$

Step2: Calculate the exponent

$(-4)^3 = -64$

Step3: Multiply by 13

$13\times(-64) = -832$

Step4: Divide 2 by 3

$2\div3 = \frac{2}{3}$

Step5: Combine all terms

$68 - (-832) + \frac{2}{3}$
$= 68 + 832 + \frac{2}{3}$
$= 900 + \frac{2}{3}$

Answer:

$\frac{2702}{3}$ or $900\frac{2}{3}$
