Analytical Lab 1 Paper

I’m stuck on 5,6 and 10 please help

I only need the slopes column if possible anything else is extra.

1. Evaluate the following expression to the nearest whole number: 6⁶ × 6⁻⁴ 2. Evaluate the following expression to the nearest whole number: log(10⁵) 3. Evaluate the following expression: 18 + (6 - 2)² × 3 4. Express the following sum as a decimal to four significant figures: 1/3 + 3/4 = 5. Solve for the positive value of x that satisfies the following equation: (x + 9)(x - 2) = 60 6. Solve for x to the proper number of significant figures: (0.500)^(x/4.50) = 0.100 7.
