Evaluate three plus five to the 𝑥
power if 𝑥 equals two.
In this case, we have the
expression three plus five to the 𝑥 power. In order to evaluate this
expression, we substitute the number two in for 𝑥 so that we have three plus five
squared. Five squared is five times five,
which is 25. We add three to 25 to get 28, which
tells us that three plus five to the 𝑥 power is equal to 28 when 𝑥 equals two.
