5a x a = 5a2
5a times 5a would equal 25a^2.
The answer depends upon what the "x" here means. x is commonly used in algebra to denote a variable. However "x" is also a symbol used to mean multiplication. If the first then 5xa means 5 multiplied by x multiplied by a. If the second then 5xa means 5 multiplied by a. This is usually written simply as 5a.
what is 5a x 3 x 2b
5a^(3) if the x means multiplication. 5a^(3)x^(3) if the x is a variable.
urmom
5a + 4b - 3a =(5a - 3a) + 4b =2a + 4b =2 (a + 2b)
Since they are like terms, 5a*3a=15a. Find out what "a" is equal to and multiply it by 15. Then, and only then, will you get your answer.
5a times 3a minus 8a = (5*3)*a2 - 8a = 15a2 - 8a
The F is a F sharp.Play this:DX7F X6DFAD B A D B AB X 5A X 3 then AGX6 then A and Gfly i i iB X 5A X 3 then B and AG X 8A G F Ethen do it all again.
The exponent tells how many times the base is used as a factor. 23 = 2 x 2 x 2
2x+a=p 2x=p-a x=.5p-.5a
