Example This number is HUGE!! It is much easier to write the number in standard form x 10 A number between 1 and 10 (but not including 10) A power of

Example This number is Tiny!! It is much easier to write the number in standard form x 10 A number between 1 and 10 (but not including 10) A power of

Let’s try some together... a) b) c) d)

YOUR TURN! a)7000 b)86000 c) d) e)0.056 f)

Multiply two numbers 4 x x 3 x x 3x x 10 4 Numbers Powers of 10 = 12 x ADD powers = 1.2 x 10 1 x = 1.2 x NOT Std Form!

Let’s try some together... (2x 10 2 ) x (4 x 10 5 ) (8 x 10 8 ) x (2 x ) (25 x 10 8 ) ÷ (5 x 10 2 )

Try these (3 x 10 4 ) x (2 x 10 5 ) 2.(4 x 10 3 ) x (3 x 10 5 ) 3.(7 x 10 4 ) x (2 x ) 4.(8 x 10 6 ) ÷ (2 x 10 2 ) 5.(20 x 10 4 ) ÷ (4 x 10 8 )
