Check Explanation
Explanation
1) (-3 × 4)⁰ = (-12)⁰ = 1 (any number raised to 0 gives 1)
2)
3) 4 × 0 = 0 (any number multiplied by 0, gives 0)
4) x⁻⁸.x⁴ = x⁻⁸⁺⁴ = x⁻⁴
5) 2.3 = 6 OR 2⁻³ = (1/2³) = (1/8)
6) 7⁻² (-3)² = (1/7²) (9) = (1/49) (9) = (9/49)
7) (a - 3)/(b - 2) where a = 5 and b = 6
[tex]\begin{gathered} \frac{a-3}{b-2} \\ a=5,b=6 \\ \frac{a-3}{b-2}=\frac{5-3}{6-2}=\frac{2}{4}=\frac{1}{2} \end{gathered}[/tex]8) 9x²y⁻³ = (9x²/y³)
where x = 5 and y = 3
[tex]\begin{gathered} \frac{9x^2}{y^3} \\ x=5,y=3 \\ \frac{9x^2}{y^3}=\frac{9(5^2)}{3^3}=\frac{9\times25}{27}=\frac{25}{3} \end{gathered}[/tex]9) 14x⁻² = (14/x²)
where x = 7
[tex]\begin{gathered} \frac{14}{x^2} \\ x=7 \\ \frac{14}{x^2}=\frac{14}{7^2}=\frac{14}{49}=\frac{2}{7} \end{gathered}[/tex]10) 16 - 5 = 11
Hope this Helps!!!
