Study Notes
Algebraic Expressions
- The value of $8\frac{4}{17^2 - 3^2 - 6^3} = \frac{x}{3}$ needs to be determined.
- The value of $27 \times \frac{390}{13} - 40% of 760 + 4^3 = x$ needs to be determined.
- The value of $45% of 180 + \sqrt{144} \times 8 = x^2 + 70% of 80$ needs to be determined.
- The value of $\sqrt{529} \times 5 - 15% of 220 + x = 120% of 160$ needs to be determined.
Exponents and Roots
- The value of $(0.512) \times \frac{2}{5} \times (0.8)^3 \div (0.4096) = (0.8)^{\frac{x}{5}}$ needs to be determined.
