Can someone correct these for me..plz...
MY answer: p^14
Write using positive exponents only.
MY answer: (1)/(b^6)
Write 1.81 X 10^-2 in standard notation
My answer. 0.0181
Subtract 2x-3x^2+5x^3 from 5x^3+4x-x^2
My answer is: 2x^2+2x
My answer is: -8x^2+10x
I doubt I know any of this since im a yr9 but we learnt some of this. Im somewhat confused by the brackets though.
(a) p^11 ^4 or perhaps p^11 + ^4
(d) what does x equal though?
Oh sorry how foolish and not much my answer is but I havent heard of the others or know how to.
All look OK! Good job!
I think you meant for #5:
which would give you the answer you stated.
yes, thank you....that is what i meant towards the parenthesis i forgot that extra )
