You have to multiply whats outside the parenthesis with everything that is inside, so

x^{-3}y^0.(x^2-3x^5y^4)

x^{-3}y^0.x^2-x^{-3}y^0.3x^5y^4

Multiplication of same bases we sum the exponents

x^{-3+2}y^0-3x^{-3+5}y^{0+4}

x^{-1}.1-3x^2y^4

x^{-1}-3x^2y^4

Alternative B.

3(x+6)=2(4x+14)<br> what is the value of x?
GrogVix [38]
Hi there

3(x + 6) = 2(4x + 14)
3x + 18 = 8x + 28
3x - 8x = 28 - 18
-5x = 10
x= 10/-5
x = -2


Here it is :)


Merry Christmas
