Question

А)5x⁴умножить(-3x²y³) б)(-2xy⁴)⁴ решите срочно пожалуйста!!!!!

Answer 1

А)5х⁴×(-3х²у³)=(5×(-3))⁴*²×у³= -15в восьмой степени ×у³

Answer 2

а)

5x⁴ * (-3x²y³)

= -15x⁶y³ (when multiplying x^4 and x^2 we add the exponents to get x^6, and when multiplying x^6 and y^3 we multiply the coefficients and add the exponents of x and y)

б)

(-2xy⁴)⁴

= 16x⁴y¹⁶ (when raising a power to a power we multiply the exponents, so we get (-2)^4 * x^4 * (y^4)^4 = 16x^4y^16)

I hope this helps!
