Answer:
Step-by-step explanation:
7.
2y² * 3x = 6xy²
8.
4v³ * vu²
[tex]= 4 \times 1 \times (v^{3+1})( u^2)[/tex]
= 4v⁴u²
9.
4a³b² * 3a⁻⁴b⁻³
[tex]= 4 \times 3 \times a^{(3+(-4))} \times b ^{(2+(-3))}[/tex]
= 12a⁻¹b⁻¹
[tex]= \dfrac{1}{12ab}[/tex]
10.
x²y⁻⁴ * x³y²
[tex]= x^{2+3}y^{(-4)+2}[/tex]
[tex]= x^{5}y^{-2}[/tex]
[tex]= x^{5} \times \dfrac{1}{y^{2}}[/tex]
11.
(x²)⁰ = 1
12.
(2x²)⁻⁴
[tex]= (2^{-4} \times x^2^{(-4)})[/tex]
[tex]= \dfrac{1}{16x^8}[/tex]
