Question

find the value of the expression
$5^2 + 5^w - z^v$
for $v = 2$, $w = 2$, and $z = 7$.

Explanation:

Step1: Substitute given values

Substitute $v=2$, $w=2$, $z=7$ into the expression:
$5^2 + 5^2 - 7^2$

Step2: Calculate each exponent term

$5^2=25$, $5^2=25$, $7^2=49$
Expression becomes: $25 + 25 - 49$

Step3: Compute sum and difference

$25+25=50$, then $50-49=1$
