|
2^3 x 2^3 =
(2 x 2 x 2) x (2 x 2 x 2) = 2^6 = 64
Evaluate (2^3)^2
|
The constant factor by which all dimensions of an object are enlarged
What does scale factor mean?
|
(3x-4) + (2x+5) = 3x +2x -4 +5
= 5x-1
Add 3x-4 and 2x+5

What is the formula for S of a prism?
|
3.64
Calculate -1.4(-2.6)
|
Because you time the exponent inside the bracket, and outside the bracket.
Why does (4^2)^5 = 4^10
|
3cm x 3 = 9cm
7cm x 3 = 21cm
Multiply each measurement by a scale factor of 3.
3cm, 7cm |
(6x-3) + (-2x -4) =
6x-2x + -3-4 = 4x + -7
Add 6x-3 and -2x-4

It is a shorter way of writing repeated multiplication, using a base and an exponent.
What does exponential form mean?
|
50cm x 0.5 = 25cm
88cm x 0.5 = 44cm
Reduce the measurements by a scale factor of 0.5
50cm, 88cm |
7a + -3a + 6a = 10a
-6b + 7b + 2b = -1b 10a + -1b
