Im not kidding. Our exam is tomorrow, i need an 80% to pass, i have no clue about exponent laws, or the formulas for area, volume, surface area, Lateral surface area(can someone tell me the difference??) and those are major parts of the exam and i spent all day yesterday learning about line equations. HELP! i need desperate help with exponent laws. The first five anyways.
I just need explaining in english. Or normal math terms.
