I give out medals

jim_thompson5910 · Answer

Replace each 'a' with 4. Then use PEMDAS to calculate


$$\Large 5a^4 = 5*(a)^4$$

$$\Large 5a^4 = 5*({\color{red}{a}})^4$$

$$\Large 5a^4 = 5*({\color{red}{4}})^4$$

$$\Large 5a^4 = ???$$

what about the 2

jim_thompson5910 · Answer

`what about the 2`
What do you mean? I don't see any "2" in the problem

bryanbarrett02 · Answer

sorry a=2

jim_thompson5910 · Answer

oh, you would follow the same idea. But instead of '4', you'd use '2'

jim_thompson5910 · Answer

If a = 2, then...


$$\Large 5a^4 = 5*(a)^4$$

$$\Large 5a^4 = 5*({\color{red}{a}})^4$$

$$\Large 5a^4 = 5*({\color{red}{2}})^4$$

$$\Large 5a^4 = ???$$
