|
volume of a prism |
= A (base or end face) × H or L |
|
|
volume of cylinder |
= 3.14 × r² × h |
|
|
volume of a pyramid |
=⅓ × A (base) × height |
|
|
volume of a cone |
= ⅓ × 3.14 × r² × h |
|
|
volume of a sphere |
= 4/3 × 3.14 × r³ |
|
|

|
|
pythagorus formula |
c² = a² + b² |
|
|
indices rule 1 |
to multiply powers of the same number, you add the powers - x² × x³ = x²+³ = x⁵ |
|
|
coefficients with rule number one |
dela with numbers first then deal with powers (2x³ × 3x⁴ = 6x⁴+³ = 6x⁷) |
|
|
indices rule 2 |
to divide powers of the same number, you subtract the powers- x⁴ ÷ x³ = x⁴-³ = x¹ = x |
|
|
coefficients of rule two |
deal with numbers first (8x⁷/2x² = 4x⁷-² = 4x⁵) |
|
|
indices rule 3 |
to take 'powers' from 'powers' of a number, you multiple the indices - (x²)³ = x²×³ = x⁶ |
|
|
coefficients for rule 3 |
deal with power to the number first then deal with indices - (2x³)⁴ = 2⁴×(X³)⁴ = 16X × X³×⁴ = 16x¹² X³)⁴ = 16X × X³×⁴ = 16x¹² = 16X × X³×⁴ = 16x¹² |
|
|
indices rule 4 |
a⁰ = 1 for example 10⁰ = 1 or (c⁴×c-⁴)³ = c⁴+(-⁴)³ = (c⁰)³ = 1 |
|
|
indices rule 5 |
a to the power of negative 4 = 1 over a to the power of positive 4 |
|
|
indices rule 6 |
denominator = root numerator = power |
|
|
indices rule 6 |
negative must be nust change to positive power |
