Standard form essentially means to not have any symbols such as "x","÷", or "power".
The equation would be written as:
(64 x 10) ^4
Then
(640) ^ 4
Which equals: <span>167772160000</span>
Your answer should be y=8x2
The answer would be $25.22 the way to do this would be to divide 7.76 by 4 and then you would multiply that answer by 13 so it would be the 4th answer
Idk becuase i searched it up and got one fourth
