WHEN MULTIPLYING LIKE BASES, YOU ADD THE EXPONENTS FOR EXAMPLE: NOW YOU TRY:

© T Madas. Divide the following numbers in the ratio given 16 at 3 : at 1 : at 3 : at 1 : at 2 : at 3.

 To add numbers in scientific notation: 1) Add the constants 2) Keep the exponent the same  Example: (2.1 x 10 5 ) + (3.2 x 10 5 ) = ( ) x 10.

Inverse Operations ExpressionInverse Operation How do you get the variable by itself? x + 5 x x x ÷ 20 x3x3.

© T Madas. Every length has doubled The Scale Factor is 2 Object Image Scale factor is the number of times the lengths of the original shape have been.

Integers All whole numbers and their opposites including the number 0.

Divide. Evaluate power – 3 = – 3 EXAMPLE – 3 = 3 2 – – 3 = 6 – 3 Multiply. Evaluate expressions Multiply and divide from.

Substitution 1. Calculate a + b – c If a = 10 b = 8 and c = 12 When g = 6 and h = 14 2t 2 – 4t 2 t = 4 and t =6 ½ w + ¼ h w = 12 and h = 20.
