Evaluate three plus five to the 𝑥 power if 𝑥 equals two.
00:00:06.833 --> 00:00:11.363
In this case, we have the expression three plus five to the 𝑥 power.
00:00:11.973 --> 00:00:22.283
In order to evaluate this expression, we substitute the number two in for 𝑥 so that we have three plus five squared.
00:00:22.893 --> 00:00:26.493
Five squared is five times five, which is 25.
00:00:27.093 --> 00:00:38.053
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.
