Answer 1

Answer:

$\boxed{\sf A)\: -16}$

Step-by-step explanation:

$\sf 5+\left(3\left(2-\sqrt{81}\right)\right)$

$\bigstar$ Calculate the square root of 81 = 9

$\longrightarrow$ $\sf 5+3(2-9)$

$\bigstar$ Subtract 9 from 2= -7

$\longrightarrow$ $\sf 5+3(-7)$

$\bigstar$ Multiply 3 and -7 = -21

$\longrightarrow$ $\sf 5-21$

$\bigstar$ Subtract 21 from 5 = -16

$\longrightarrow$ $\sf -16$
