Question

I have couple question I need help on I have an image of it

Answer 1

Check Explanation

Step-by-step 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

`\begin{gathered} (a-3)/(b-2) \\ a=5,b=6 \\ (a-3)/(b-2)=(5-3)/(6-2)=(2)/(4)=(1)/(2) \end{gathered}`

8) 9x²y⁻³ = (9x²/y³)

where x = 5 and y = 3

`\begin{gathered} (9x^2)/(y^3) \\ x=5,y=3 \\ (9x^2)/(y^3)=(9(5^2))/(3^3)=(9*25)/(27)=(25)/(3) \end{gathered}`

9) 14x⁻² = (14/x²)

where x = 7

`\begin{gathered} (14)/(x^2) \\ x=7 \\ (14)/(x^2)=(14)/(7^2)=(14)/(49)=(2)/(7) \end{gathered}`

10) 16 - 5 = 11

Hope this Helps!!!
