Question

Simplify each expression 4+√121 -2×3^3/|-19-2(-8)

Answer 1

Answer: =7

Step-by-step explanation:

$4+\sqrt{1}\times \:21-2\times \frac{3^3}{\left|-19-2\left(-8\right)\right|}$

$=4+1\times \:21-2\times \frac{3^3}{\left|-19-2\left(-8\right)\right|}$

$=4+1\times \:21-2\times \frac{3^3}{\left|-19+2\times \:8\right|}$

$=4+21-2\times \frac{3^3}{\left|2\times \:8-19\right|}$

$=4+21-3^2\times \:2$

$=7$
