Question

find the value of the expression
$u^2 + w \div (z \div v)$
for $u = 3$, $v = 2$, $w = 78$, and $z = 52$.

Explanation:

Step1: Substitute given values

$u=3, v=2, w=78, z=52$ into the expression:
$3^2 + 78 \div (52 \div 2)$

Step2: Calculate innermost parentheses

Compute $52 \div 2$ first:
$52 \div 2 = 26$

Step3: Calculate division next

Compute $78 \div 26$:
$78 \div 26 = 3$

Step4: Calculate the square term

Compute $3^2$:
$3^2 = 9$

Step5: Add the remaining terms

Add the results from Step3 and Step4:
$9 + 3 = 12$

Answer:

12
