1) You'll have to get raid of the fraction by multiplying 10ac by 11, x/11 by 11 which the 11's cancels out and -3 multiplied by 11 .
2)Now you have 10ac -x = -33. Add x on both sides of the equal sign you get 10ac = -33 + x
3) Divide both sides by 10c to get "a" by itself, so "a" = -33+x divided by 10c
Answer:

Step-by-step explanation:

6 - 3 = 3
keep the base same, therefore

Hope this helps!
Expanding (2x² + y²)⁴ with Pascal triangle or using binomial theorem gives:
(2x² + y²)⁴ = 16x⁸ + 32x⁶y² + 24x⁴y⁴ + 8x²y⁶ + y⁸
I mean I think so I’m not completely sure it’s a really hard question
