Let’s first expand out before factorising completely.

(2a + 2b) (2a + 2b) =

4a^2 + 8ab + 4b^2

Add to 4b^2 - a^2

4a^2 + 8ab + 8b^2 - a^2

= 3a^2 + 8ab + 8b^2
=8b (a + b) + 3a^2
=8b (a + b + 3a^2/8b)
=8b (b+ a(1+3a/8b))

This might be wrong lol.

What is 8.57x10-⁴ in standered form ?
marusya05 [52]

Kaleerain5,

In order to get your answer you must remember that if the exponent is negative move to the left and if the exponent is positive you have to move to the right.

  • 8.57 \times 10^{-4}
  • The exponent is negative so move to the left:
  • 8. = .8 = .08 = .008 = .0008
  • = .000857

Therefore your answer is ".000857."

Hope this helps!
